The base-catalysed eliminations of the vinylogous β-hydroxysilanes 7, 9, 11 and 12 are stereospecifically syn, giving largely the trans,trans-diene 8 from 7 and 11, the cis,trans-diene 10 from 9, and the trans,cis-diene 13 from 12; when a cis double bond is produced, it is selectively placed adjacent to the carbon atom that originally carried the hydroxy group.
插烯β-羟基硅烷的碱催化冲销7,9,11和12是立体有择地顺式,给予很大程度上反式,反式-二烯8从7和11,在顺式,反式-二烯10从9,和反式,顺式二烯13从12 ; 当产生顺式双键时,它被选择性地放置在与最初带有羟基的碳原子相邻的位置。
