Cyanoferrocenes as redox-active metalloligands for coordination-driven self-assembly

Ferrocene-based Lewis bases have found utility as metalloligands in a wide variety of applications. The coordination chemistry of cyanoferrocenes however, is underexplored. Herein, we describe a new synthetic protocol for the generation of cyanoferrocenes. The coordination chemistry of these metalloligands to [Cu(NCMe)4][PF6], [(PPh3)2Cu(NCMe)2][PF6] and [(dppf)Cu(NCMe)2][PF6] salts has been explored, providing crystallographic evidence of cluster and polymeric forms of 1,1?- and 1,2-dicyanoferrocene complexes. The stability of the complexes and ligand dissociation were found to be strongly solvent-dependent.

Redox active alkenyl-bridged bi- and trinuclear arene-Cr(CO)3-complexes by Horner-Emmons-Wadsworth olefinations

Alkenyl-bridged arene-Cr(CO)3-complexes 2 are readily synthesized in good yields by Horner-Emmons-Wadsworth (HEW) olefinations from Cr(CO)3-complexed benzylphosphonates 1 and organometallic aldehydes. The resulting bi- and trinuclear homo-and heterometallic complexes display a strong electronic coupling between the metal fragments as shown by a strong correlation of the CO resonances in the carbon NMR spectra and the chromiumcarbonyl metal-ligand charge transfer (MLCT) bands in the UV/vis spectra. Furthermore, the electrochemistry of the oligonuclear complexes 2 was investigated by cyclic voltammetry.

Organometallic-Organic Hybrid Crystals from Ferrocenyl Dipyridine and Binaphthol: Different Crystal Structures and Nonlinear Optical Properties Depending upon the Reaction Medium and Optical Purity of Binaphthol

The hydrogen bond directed molecular recognition between 1,1?-bis(ethenyl-4-pyridyl)-ferrocene (1) and (¡À)-1,1?-binaphthol (2)/(-)-1,1?- binaphthol ((-)-2) has been studied by cocrystallization in different solvents. Single-crystal X-ray structures reveal that 3:2, 2:1, and 1:1 complexes (3, 4, and 5, respectively) of 1,1?-bis(ethenyl-4-pyridyl)ferrocene (1) and (¡À)-1,1-binaphthol (2) are formed in tetrahydrofuran, methanol, and ethanol, respectively. 5 has a noncentrosymmetric packing arrangement, and an efficiency of 0.3 times that of urea in second-harmonic generation has been measured at 1295 nm. An X-ray crystal structure of 6, 1:1 complex of 1 with (-)-2 in ethanol, reveals that all the molecular dipoles are aligned in the same direction (i.e, a polar crystal), but 6 has modest nonlinear optical properties (ca. 0.4 times that of urea).

Design and synthesis of new functional compounds related to ferrocene bearing heterocyclic moieties. A new approach towards electron donor organic materials

The synthesis of heterocyclic systems incorporating more than one ferrocene unit was shown to be a facile and convenient route for the synthesis of new ferrocene-heterocycles. Hydrazide 2 was prepared and cyclized to oxadiazole, triazole, and pyrazole using the procedures described in this context with good yields. A pyrazolone derivative could not be obtained and instead a hydrazone derivative 17 was isolated. Hydrazide 2 was condensed with aromatic aldehydes and ferrocene-1,1?-dicarbaldehyde derivatives to give the corresponding hydrazones 11a-c and dihydrazones 12, 14 and 18 in high yields. Cyclic voltammetry (CV) of the selected ferrocene-heterocycles 8 and 9 was studied comparing with the parent ferrocene and acetylferrocene. The CV of the compound 8 revealed an additional, quasireversible, one-electron oxidation wave at 849 mV, corresponding to the second ferrocene unit connected to the oxadiazole ring through the SCH2CO spacer.

Synthesis and hydrolysis of [alkenyl(alkoxy)carbene]manganese complexes: Evidence for a transient allylic intermediate on the way to alpha,beta-unsaturated aldehydes

A variety of alkenylcarbene complexes [Cp'(CO)2Mn= C(OEt)CH=CHR] (3) (Cp’ = TiS-MeCsH4) was obtained in a straightforward manner upon aldol condensation of [Cp'(CO)2Mn=C(OEt)CH3] (1) with aromatic and alpha,beta- unsaturated aldehydes RC(H)O (2). The reaction is totally stereoselective, giving (E)- or (all-E)-alkenylcarbenes only. The protonation of 3 at low temperature followed by reaction with water affords the alpha,beta-unsaturated aldehyde complexes [Cp'(CO)2Mn(n2-RCH=CHCHO] (5), from which the aldehydes RC(H)=C(H)C(H)O (6) were displaced by acetonitrile. The intermediate aldehyde complexes are shown to result from the hydrolysis of a transient cationic pi- allyl species [Cp'(CO)2Mn(n3-RCHCHC(OEt)H]+ ([4]+) formed upon protonation of 3.

Chemical and electrochemical formation of pseudorotaxanes composed of alkyl(ferrocenylmethyl)ammmonium and dibenzo[24]crown-8

Protonation of p-xylylaminomethylferrocene (1) and n- hexylaminomethylferrocene (2) by HCl and NH4PF6 forms the ferrocenylmethyl(alkyl)ammonium salt. Inclusion of the compounds by dibenzo[24]crown-8 (DB24C8) produces [2]pseudorotaxanes, [(DB24C8)(1-H)] +(PF6) and [(DB24C8)(2-H)]+(PF6), respectively. X-ray diffraction of the former product indicates an interlocked structure composed of the axis and the macrocyclic molecule. Intermolecular N-H…O and C-H…O interactions and stacking of the aromatic planes are observed. [(DB24C8)(1-H)]+(PF6), in the solid state, is characterized by IR spectroscopy and elemental analyses. A similar reaction of 1,1?-bis(p-xylylaminomethyl)ferrocene (3) forms a mixture of [2] and [3]pseudorotaxanes, [(DB24C8)(3-H2)]2+(PF 6)2 and [(DB24C8)2(3-H2)] 2+(PF6)2. The latter product having two DB24C8 molecules is isolated and characterized by X-ray crystallography. Formation of these pseudorotaxanes in a CD3CN solution is evidenced by 1H NMR and mass spectrometry. Electrochemical oxidation of 1-3 at 0.4 V (vs Ag+/Ag) in the presence of TEMPOH (1-hydroxy-2,2,6,6- tetramethylpiperidine) and DB24C8 affords the corresponding pseudorotaxanes. The ESR spectrum of the reaction mixture indicates the formation of a TEMPO radical in high yield. Details of the conversion of the dialkylamino group of the ligand to the dialkylammonium group are investigated by using a flow electrolysis method linked to spectroscopic measurements. The proposed mechanism for the reaction involves the ferrocenium species, formed by initial oxidation, which undergoes electron transfer from nitrogen to the Fe(III) center, producing a cation radical at the nitrogen. Transfer of hydrogen from TEMPOH to the cation radical and inclusion of the resulting dialkylammonium species by DB24C8 yields the pseudorotaxanes.
