Ferrocenyl thioesters

Ferrocenyl thiols of the formula STR1 wherein n is an integer of from 2 to 4 are prepared by reacting a compoundf the formula STR2 with thioacetic acid, STR3 at elevated temperatures in the presence of a free radical initiator to produce a thiol ester of the formula STR4 and then hydrolyzing the thiol ester to produce the thiol. The thiols are useful as non-migrating burning rate modifiers for unsaturated rubber-based propellants.

Conditional Copper-Catalyzed Azide?Alkyne Cycloaddition by Catalyst Encapsulation

Supramolecular encapsulation is known to alter chemical properties of guest molecules. We have applied this strategy of molecular encapsulation to temporally control the catalytic activity of a stable copper(I)?carbene catalyst. Encapsulation of the copper(I)?carbene catalyst by the supramolecular host cucurbit[7]uril (CB[7]) resulted in the complete inactivation of a copper-catalyzed alkyne?azide cycloaddition (CuAAC) reaction. The addition of a chemical signal achieved the near instantaneous activation of the catalyst, by releasing the catalyst from the inhibited CB[7] catalyst complex. To broaden the scope of our on-demand CuAAC reaction, we demonstrated the protein labeling of vinculin with the copper(I)?carbene catalyst, to inhibit its activity by encapsulation with CB[7] and to initiate labeling at any moment by adding a specific signal molecule. Ultimately, this strategy allows for temporal control over copper-catalyzed click chemistry, on small molecules as well as protein targets.

Mono- and 1,1′-disubstituted aza ferrocenyl compounds: Evidence for an original electroactive fluorescent species

New azaalkyl or azacrown ferrocenyl compounds containing a C5H4COCC- linkage are accessible from mono- or diacetylferrocene upon treatment with the appropriate aldehydes (CHOC6H4-p-R, R = NEt2, N-aza-15-crown-5). Preliminary results concerning the electrochemical behaviour of complexes [(C5H5)Fe(C5H4COCH=CHC6H4NEt2)] (3a), [Fe(C5H4COCH=CHC6H4NEt2)2] (5a), the novel ferrocenophane [Fe(C5H4COCH2)2CHC6H4NEt2] (6a) and its protonated species [Fe(C5H4COCH2)2CHC6H4NHEt2][BF4] (7a), are reported.

Assessing the influence of phosphine substituents on the catalytic properties of self-stabilised digold(i) complexes with supporting ferrocene phosphinonitrile ligands

Gold(i) phosphine complexes are often used in catalysis, but the role of their auxiliary ligands still remains poorly understood. Thus, building on our previous research, we prepared a series of Au(i) complexes [Au2(mu-R2PfcCN)2][SbF6]2 (fc = ferrocene-1,1?-diyl) to assess the effect of phosphine groups PR2 on the catalytic properties of these highly catalytically active, dimeric compounds. Catalytic testing in Au-mediated cyclisation of N-propargyl amides to 2-substituted 5-methyleneoxazolines showed that weaker donating phosphines gave rise to more active, albeit partly destabilised, catalysts. Nevertheless, thanks to their self-stabilisation by reversible nitrile coordination, [Au2(mu-R2PfcCN)2]+ cations readily converted into catalytically active species (by dissociation) and, in addition, remained catalytically active even at very low metal loadings. The experimental results were supported by the trends in 1JPSe coupling constants for R2P(Se)fcCN as a measure of ligand basicity, and by DFT calculations.

Substituent influence on charge transfer interactions in alpha,alpha?-Diferrocenylthiophenes

Within a series of alpha,alpha?-diferrocenylthiophenes, the influence of electron-withdrawing substituents at the ferrocenyl moieties and electron-donating functionalities at the thiophene bridge on the electronic behavior was studied. The synthesis of the appropriate 2,5-fc2-cC4H2S and 2,5-fc2-3,4-(OCH2CH2O)-cC4S compounds (fc = Fe(eta5-C5H4)(eta5-C5H4R); R = H (1, 5), 3,5-(CF3)2-cC6H3 (2, 6), CHO (3, 7), C?N (4, 8)) was carried out using the Negishi C,C cross-coupling protocol to effect the coupling of the thiophene and the ferrocenyl moieties. The corresponding diferrocenylthiophenes were characterized spectroscopically. Within this context, the structural properties of 2-5, [5][B(C6F5)4], 6, and 8 in the solid state were investigated by single-crystal X-ray diffraction studies. Electrochemical investigations of thiophenes 2-8 demonstrated an increasing redox separation and hence thermodynamic stability of the corresponding mixed-valent species in the series 1 < 3 < 5 < 4 ? 2 < 6 < 7 < 8. Moreover, UV/vis/near-IR and infrared spectroelectrochemical studies verify these observations. These studies further reveal a valence trapped situation in corresponding mixed-valent species and allow a class II classification according to Robin and Day.

Conformational analysis of the [(C5H4CR?R?)2m]2+ dications (M = Ru, Os) as a tool for determining their onium or dicarbocation structure

The [(Me2CC5H4)2M]2+ and [(Me(H)CC5H4)2M]2+ dications (M = Ru, Os) were generated and their precursors, dicarbinols, were synthesized. 1H NMR spectral analysis showed that the former dications have a dicarbocation structure. For the [(Me(H)CC5H4)2M]2+ dications, the energies of both the onium and dicarbocation structures are close, and compounds of both types can be simultaneously observed in solution.

Scanning Electrochemical Microscopy with Forced Convection Introduced by High-Precision Stirring

In the present report the well-known advantages of hydrodynamic mass transport in electrochemical systems are used in combination with scanning electrochemical microscopy (SECM). The hydrodynamic SECM system integrates a high-precision stirring device into the experimental setup. The well-defined stirring of the SECM electrolyte results in steady state diffusion layer characteristics in the vicinity of large substrate electrodes operated in chronoamperometric measuring mode. For a range of rotation frequencies of a rotating cylinder the thickness and the stability of the diffusion layer was studied by hydrodynamic SECM in the substrate generation/tip collection (SG/TC) as well as in the competition mode using ferrocene methanol as redox mediator. Different UME probe dimensions ranging from Pt diameters of 20 mum down to 0.6 mum were used. The smallest probe with dPt = 0.6 mum was found most suitable for these studies due to the almost convection-independent amperometric response associated with submum electrodes. Additionally, preliminary studies of hydrodynamic SECM imaging of a 2 mm Pt disk electrode surface in the SG/TC mode based on in situ produced hydrogen as a mediator are presented. Comparative images measured in the conventional positive feedback mode in quiescent solution show that hydrodynamic SECM offers attractive complementary information.

alpha-Ferrocenylalkyl carbonates: Reagents for ferrocenylalkylation reactions under mild neutral conditions

alpha-Ferrocenylalkyl carbonates were demonstrated to be the species for ferrocenylalkylation reactions. The alpha-ferrocenylalkyl carbonates FcCH(R)OCOOEt (1a-c, Fc?=?ferrocenyl) were easily generated in situ by a reaction of the alpha-ferrocenyl substituted alcohols FcCH(R)OH (5a-c) with equimolar amounts of n-BuLi followed by EtOCOCl in THF or Et2O at 20?C. Due to the low thermal stability, carbonates 1a-c readily undergo a heterolytical decay furnishing the alpha-ferrocenyl carbocations FcCH(R)+ (2a-c) and carbonate anion R’OC(O)O? (3). The last one reversibly loses a molecule of CO2 giving rise anion EtO? that is capable of deprotonating a pre-nucleophile NuH (MeCOCH2COMe, dimethyl malonate, etc.) giving rise the corresponding nucleophile Nu?. The interaction between 2a-c and Nu? produces the alpha-ferrocenylalkylation products FcCH(R)Nu (4a-c) in moderate to high yields. The sequence above is a novel alpha-ferrocenylalkylation procedure easily proceeding under mild and neutral conditions. Due to these features, it may be useful for alpha-ferrocenylalkylations of either thermally labile compounds or the substrates susceptible to acidic conditions. The stability of carbonates 1a-c was found to decrease as the stability of the corresponding carbocations 2a-c increases. With 2-mercapto-1-methylimidazole, the alpha-ferrocenylalkylations proceed as the N-alkylation processes.
