Synthesis of derivatives of (alpha-(dimethylamino)ethyl)ferrocene via lithiation reactions and the structure of 2-(alpha-(dimethylamino)ethyl)-1,1?,3-tris(trimethylsilyl)ferrocene

Dilithiation of Fe(C5H4CHMeNMe2)(C5H5) (1) with BuLi is predominantly homoannular but with BuLi/TMED is heteroannular. Heteroannular dilithiation predominates in the reaction of BuLi/TMED with Fe(C5H3(CHMeNMe2)SiMe3-1,2)(C 5H5), Fe(C5H3(CHMeNMe2)SiMe 3-1,2)(C5H4SiMe3), and Fe(C5H2(CHMeNMe2) (SiMe3)2-1,2,3,)(C5H4SiMe 3) (11). The lithioferrocenes react with ClSiMe3 to afford isolable products although some mixtures of isomers are difficult to characterize. The [3]ferrocenophane Fe(C5H3(CHMeNMe2)S3-1,2,3)(C 5H4) is obtained from 1 as are [Fe(C5H5)(C5H3(CHMeNMe 2)-1,2)]xQ (x = 2, Q = PPh; x = 1, Q = SMe; x = 1, Q = PPhCMe3 (only one diastereomer because of strong chiral induction)) and Fe(C5H4CHMeNMe2)(C5H 4AsPh2). Crystals of 11 are monoclinic: a = 17.800 (2) A, b = 11.760 (1) A, c = 13.931 (2) A, beta = 107.142 (5), Z = 4, space group P21/n. The structure was solved by conventional heavy-atom methods and was refined by full-matrix least-squares procedures to R = 0.054 and Rw = 0.061 for 2745 reflections with I ? 3sigma(I).

Synthesis of planar chiral ferrocenyl 1,3-diamines and 1,3-amino ethers

The efficient syntheses of novel planar chiral 1,3-diamines and 1,3-amino ethers with an oxy or amino function directly bound to the cyclopentadienyl ring of ferrocene has been developed. The key reaction is the Cu2O promoted substitution of of (pR)-diisopropyl-2-iodoferrocenecarboxamide with either phthalimide or AcOH to introduce nitrogen or oxygen functionality onto the cyclopentadienyl ring. The enantiomerically pure iodoferrocene derivative is available from the known enantioselective ortho-lithiation of N,N-diisopropylferrocenecarboxamide with n-BuLi sparteine, In the course of these studies the synthesis of a novel C2 symmetric C-2 dimer of N,N-dimethyl-1-ferrocenylethylamine was characterised by single crystal X-ray diffraction.

MASS SPECTROMETRY OF ?-COMPLEXES OF TRANSITION METALS XX. DIMETHYLAMINOALKYL DERIVATIVES OF FERROCENE AND CYMANTRENE; THE DETERMINATION OF THE DISTRIBUTION AND THE TOTAL CONTENT OF DEUTERIUM LABEL

The mass spectrometry behaviour of dimethylaminomethyl- and alpha-(dimethyl-amino)ethyl derivatives of cymantrene and ferrocene, their iodine methylates as well as of the deutero analogues of these compounds has been studied.It has been shown that mass spectrometry can be successfully employed for the quantitative determination of the total deuterium content in aminoalkyl derivatives of cymantrene and ferrocene, the distribution of the label between the dimethylaminoalkyl group and the metallocenyl fragment and in case of the dimethylaminomethylferrocene also between thesubstituted and unsubstituted cyclopentadienyl rings.The data on the distribution of the isotopic label were used to ascertain the mechanism of fragmentation of the dimethylaminomethylferrocene under electron impact.

A new ferrocenyl bisphosphorus ligand for the asymmetric hydrogenation of alpha-methylene-gamma-keto-carboxylic acids

Upon incorporation of a noncovalent ion pair interaction, a new chiral ferrocenyl bisphosphorus ligand t-Bu-Wudaphos was developed. t-Bu-Wudaphos can be easily synthesized with very high diastereoselectivity as a highly air stable solid. The new ligand exhibited excellent reactivities and enantioselectivities in the asymmetric hydrogenation of alpha-methylene-gamma-keto-carboxylic acids via an ion pair noncovalent interaction (up to >99% conversion, >99% ee).
