Metal alkyls triethylsilane

Imines are reduced by triethylsilane to their amines when the proper Ir orNi catalysts areemployed. Non-metal-mediated reductions of C=N groups by EtsSiH are also possible. Among these, the trifluorosulfonic acid promoted reductive amidation of aliphatic and aromatic aldehydes with EtsSiH is an excellent way to mono (V-alkylate aliphatic and aromatic amides, thioamides, carbamates, and ureas (eq 26). It is also worth noting that trifluorosulfonic acid/EtsSiH reduces acyl- and tosylhydrazones to hydrazines and 2-aminopyrimidines to 2-amino-dihydro-or 2-aminotetrahydropyrimidines (eq 27). ... 

Organosilicon compounds are largely produced by the hydrosilylation of unsaturated organic substrates [47]. Various transition metal catalysts have been used to obtain alkyl-SiR products from the reaction of H-SiRj with an alkene. Alkene insertion into an M-Si bond is recognized as a fairly common process which plays a key role in catalytic hydrosilylation processes. The reaction of 1,3-butadiene (3-6) with triethylsilane in the presence of [Cr(CO)g] under photochemical condition yields exclusively the ds-1,4-adduct, ds-l-(triethylsilyl)-2-butene (7) (Scheme 10.7) [48]. In all cases, 1-4 addition products form in major, however, in some cases 1-2 addition product (9) also forms in minor yield. Formation of product 12 can be rationalized in terms of double bond migration subsequent to the initial hydrosilylation (Scheme 10.7).
