1 quantitatively, the structure of which was characterized by X-ray analysis. The imine complexes 1 catalyzed dehydrogenativesilylation of terminal alkynes, hydrosilylation of imines and alkenes, and intermolecular hydrophosphination of alkynes. Moreover, dehydrogenative double silylation of conjugated dienes was achieved with 1.

Ru-3(CO)(12) has been shown to catalyse the coupling of silanes with thiols, alcohols and amines with turnover number (TON) and turnover frequency (TOF) of up to 200 and 50 h(-1) at 80 degrees C. IR, NMR and mass spectroscopic studies have identified a ruthenium dimer complex, [Ru(CO)(4)(SiEt3)](2) as a likely resting state of the catalyst. A mechanism involving this complex has been proposed for the siliconethiol coupling process. (C) 2012 Elsevier B.V. All rights reserved.
Dehydrogenative Silylation of Amines and Hydrosilylation of Imines Catalyzed by Ytterbium−Imine Complexes
Dehydrogenative silylation of primary and secondary amines with triphenylsilane was catalyzed by ytterbium-imine complexes, [Yb(eta(2)-Ph2CNAr)(hmpa)(n)], to give aminosilanes in good yields. In the reaction with diphenyl- and phenylsilanes, diaminosilanes were formed as major products. Whereas n- and sec-alkylamines were readily silylated, tert-alkylamines and aromatic amines exhibited lower reactivities. Moreover, hydrosilylation of imines has been achieved by using phenylsilane and the imine complexes (Ar = Ph, C6H4F-4), giving rise to mono- and diaminosilanes. The two reactions were in agreement as regards the product selectivities and yields.
