Cerium ammonium nitrate: an efficient catalyst for carbon-carbon bond formation from ferrocenyl alcohol substrate

The substitution reaction of ferrocenyl alcohol with various nucleophiles catalyzed by cerium ammonium nitrate (CAN) was investigated. This CAN-mediated direct carbon-carbon bond formation provides the corresponding products in moderate to high yields with relatively lower catalyst loading (5 mol %) at room temperature. It demonstrated a convenient synthetic protocol for the ferrocene functionalities. Crown Copyright

Nonchelated d0 zirconium-alkoxide-alkene complexes

The reaction of Cp?2Zr(OtBu)Me (Cp? = C5H4Me) and [Ph3C][B(C6F 5)4] yields the base-free complex [Cp? 2Zr(OtBu)][B(C6F5)4] (6), which exists as Cp?2Zr(OtBu)(CIR)+ halocarbon adducts in CD2Cl2 or C6D 5Cl solution. Addition of alkenes to 6 in CD2Cl 2 solution at low temperature gives equilibrium mixtures of Cp?2- Zr(OtBu)(alkene)+ (12a-l), 6, and free alkene. The NMR data for 12a-l are consistent with unsymmetrical alkene bonding and polarization of the alkene C=C bond with positive charge buildup at Cint and negative charge buildup at Cterm. These features arise due to the lack of d-pi* back-bonding. Equilibrium constants for alkene coordination to 6 in CD2Cl2 at -89 C, K eq = [12][6]-1[alkene]-1, vary in the order: vinylferrocene (4800 M-1) ? ethylene (7.0) ? alpha-olefins > cis-2-butene (2.2) > trans-2-butene (<0.1). Alkene coordination is inhibited by sterically bulky substituents on the alkene but is greatly enhanced by electron-donating groups and the beta-Si effect. Compounds 12a-l undergo two dynamic processes: reversible alkene decomplexation via associative substitution of a CD2Cl2 molecule, and rapid rotation of the alkene around the metal-(alkene centroid) axis.

Structure and Mechanisms of Formation of C6H6Fe+ Ions Produced by Electron Impact on eta5-C5H5Fe(CO)2CH3

Collisional activation (CA) mass spectrometry has been employed to show that C6H6Fe+ ions formed upon electron impact of dicarbonyl-(eta5-2,4-cyclopentadienyl)-methyliron consist of a 1:1 mixture of fulvene-iron and benzene-iron structures.Analysis of daughter-ion spectra of the deuterium-labelled analogue shows that there exist two independent fragmentation routes leading to the different ion structures.These routes differ in the sequence in the sequence in which the CO ligands and H2 are lost from the molecular ion.

Asymmetric addition of diethylzinc to aromatic aldehydes by chiral ferrocene-based catalysts

A series of chiral C1- and C2-symmetric ferrocenyl Schiff bases (1a-c), ferrocenyl aminoalcohols (2a), ferrocenylphosphinamides (2b-c), 1,1?-ferrocenyl-diol (3), and 1,1?-ferrocenyl-disulfonamide (4) were prepared and employed as base catalysts or as ligand for titanium(IV) complexes in the asymmetric addition of diethylzinc to aromatic aldehydes. High enantioselectivity up to almost 100% ee was achieved for the alkylation of benzaldehyde and p-methoxybenzaldehyde with 1 or 3. In contrast, however, the beta-aminoalcohol (2a) and phosphinamides (2b and c) that are ubiquitous classes of base catalysts for this reaction proved inefficient in our hands, regardless of the types of substrates or reaction conditions. Comparative studies show that there exist various reaction parameters governing not only chemical yields but also optical yields. These include steric and electronic environment of the substrate, the solvent, the reaction temperature, and the nature of the ferrocene moieties.

New ferrocene based dithiolate ligands

The preparation and characterization of the three ferrocene based dithiolane complexes [(eta5-C5H5) Fe(eta5-C5H4)NHC(O)(CH2)4CHS 2CH2CH2]1, [(eta5- C5H5)Fe(eta5-C5H 4)CH2OC(O)(CH2)4CHS2CH 2CH2] 2 and [(eta5-C5H 5)Fe(eta5-C5H4)NHC(O)(CH 2)CHS2CH2CH2] 3, with different spacer groups between the ferrocenyl moiety and the dithiolane unit, are reported. The complexation of 1 and 2, using the oxidative addition of the S-S bonds to Pt(0), is also described, leading to the square planar Pt(II) complexes [Pt(PPh3)2(S2CH2CH 2CH-kappa2-S,S)(CH2)4C(O) NH(eta5-C5H4)Fe(eta5-C 5H5)] 4 and [Pt(PPh3)2(S 2CH2CH2CH-kappa2-S,S)(CH 2)4C(O)OCH2(eta5-C 5H4)Fe(eta5-C5H5)] 5, respectively. The reduction of the S-S bond in 1 and 2 yields the corresponding dithiols; these can be deprotonated and treated with ClSiMe3 to prepare [(eta5-C5H5)Fe(eta5- C5H4)NHC(O)(CH2)4CH(SSiMe 3)CH2CH2(SSiMe3)] 7 and [(eta5-C5H5)Fe(eta5-C 5H4)CH2OC(O)(CH2) 4CH(SSiMe3)CH2CH2(SSiMe 3)] 9, respectively. The complexes were characterized via NMR and UV-Vis absorption spectroscopy, cyclic voltammetry and single crystal X-ray diffraction for 1 and 4.

Self-assembly via (N?I) non-covalent bonds between 1,4-diiodo-tetrafluoro-benzene and a tetra-imino ferrocenophane

The tetra-imino ferrocenophane (1) was cocrystallized with 1,4-diiodo-tetrafluoro-benzene (TFDIB). In the resulting compound 2, two of the four ferrocenophane nitrogens show interactions with the iodine atoms of TFDIB leading to a polymeric structure with extended linear alternating electron donor (1) and acceptor (TFDIB) molecule chains. For the first time, imino nitrogens are involved in this type of halogen bonding. The N?I non-covalent bonds (N?I distances 2.879(5) and 2.896(5)A; N?I-C angles 171.1(2) and 178.1(2)) are the directing interactions responsible for the observed self-assembly. The ferrocene fragments of the macrocycle are in an almost perpendicular conformation. Moessbauer spectroscopy indicates the sole presence of low spin iron (II). The temperature dependence of the magnetic susceptibility is corresponding to a quasi-diamagnetic compound.

A reaction between cynichrodenoic acid, (eta5-C5H4COOH)Cr(CO)2NO (6) and phosphorus pentachloride produces cynichrodenoyl chloride (11) in high yield.Subsequent reaction of 11 with sodium azide affords cynichrodenoyl azide (12), which undergoes Curtius rearrangement to form cynichrodenyl isocyanate (13).Subsequent hydrolysis of isocyanate 13 in aqueous KOH solution yields aminocynichrodene (14).Azide 12 also undergoes Curtius rearrangement in the presence of benzyl alcohol to produce benzyl N-cynichrodenylcarbamate (15).Reactions of acid chloride 11 with ammonia, dimethylamine or aniline lead to the corresponding carboxamides (16-18).Amide 16 is readily dehydrated to produce cynichrodenecarbonitrile (19).Reactions of acid chloride 11 with either benzyl alcohol or hydroxymethylferrocene generate the corresponding esters (20-21), whereas treatment of a tetrahydrofuran solution of 11 with pyridine affords cynichrodenecarboxylic anhydride (22) in low yield.Reactions of acetylcynichrodene (2) with organolithium reagents, leading to both carbonyl addtion and condensation products, have been investigated.Treatment of 2 with lithium diisopropylamide in diethyl ether solution produces the self-condensation product 1,3-dicynichrodenyl-but-2-en-1-one (24).Acetyl derivative 2 and benzaldehyde also undergo Claisen-Schmidt condensation in the presence of lithium diisopropylamide to afford cinnamoylcynichrodene (27).
