Transportation (2,3) de Wittig des éthers d'allyle ou crotyle et de benzyle chrome tricarbonyle
摘要:
The (2,3) Wittig rearrangement of ortho-substituted benzyl tricarbonyl chromium allyl ether occurs with complete stereoselectivity. The ortho-substituted benzyl tricarbonyl chromium E crotyl ether gives exclusively erythro diastereoisomer, the Z isomer gives a mixture (ratio 59/41) of threo and erythro diastereoisomers.

Co-ordination of benzyl alkyl ethers and sulphides to chromium tricarbonyl allows α-substitution via the corresponding α-carbanions to be achieved by suppression of the Wittig and related rearrangements.
的协调苄烷基醚和硫化物铬三羰基允许α取代经由相应的α-碳负离子由维悌希和相关重排的抑制来实现。
