摘要

Abstract Methyl groups in positions adjacent to an olefinic double bond can be metalated without cis/trans isomerisation. On the other hand configurational changes can be brought about via metalotropy; under equilibrium conditions the Z isomers (metal cis to an alkyl in β position) predominate overwhelmingly. This behaviour opens new stereoselective routes of high preparative utility.
