Reaktionen Methyl- und Trimethylsubstituierter Vinylsilane- bzw. -Disilane mit LiBut

The reactions of the vinylsilanes Me3SiVi, Me2SiVi2, Me3SiSiMe2Vi, (Me2ViSi)2 and (Me3Si)3SiVi with LiBut in n-pentane in the first step lead to α-lithioalkylsilanes of different stabilities.The secondary reactions are clearly controlled by the reaction conditions: in dilute solution the intramolecular 2,3-LiH elimination to trans-ethene derivatives R3SiCH=CHBut is dominating, and at higher concentrations intermolecular coupling reactions of the Li-alkylsilanes with further vinylsilanes occur, with elimination of LiH and formation of olefinic compounds.At higher temperatures and owing to separation processes, competitive reactions result in the formation of isobutyl derivatives, the elimination of isobutane and the cleavage of Si-Vi bonds.In spite of the complicated reaction mixture a clear interpretation of the results is presented.

TRANS ALKENES AND VINYLSILANES FROM TRANS-α-STANNYL EPOXIDES

The reaction of trans-α-epoxystannanes (1) with an excess of alkyllithium reagents was found to undergo reductive alkylation cleanly to provide trans alkenes (3) whose isomeric purities equal or exceed those of 1.A mechanistic picture for this process which involves a carbenoid intermediate is presented.

Formation and Reactions of Olefins with Vicinal Silyl and Stannyl Substituents

The silicon-tin bond in Me3SiSnR3 (R=Me, n-Bu) adds regio- and stereospecifically to 1-alkynes and also to a limited number of nonterminal alkynes when Pd(PPh3)4 is added as a catalyst.The use of the (Z)-silylstannylalkenes thus formed in synthesis either
