甲氧羰基亚甲基三苯基胂(1a)和苯甲酰基亚甲基三苯基肿(1b)与α,β-不饱和酸酯(R1CH=CR2CO2CH3;2a,R1=H,R2=H;2b,R1=CH3,R2=H;2c,R1=H,R2=CH3)反应,得到立体专一的相应环丙烷衍生物3,经水解得到4.根据构象分析,讨论了反应的机理.从1H核磁共振谱或与已知构型的化合物相比较,确定了产物的构型.

Reactions of carbomethozymethylene triphenylarsorane (la) and benzoylmethylene-triphenylarsorane (1b) with α, β-unsaturated esters (R1CH=CR2CO2CH3;2a,R1=H,R2=H;2b,R1=CH3,R2=H;2c,R1=H,R2=CH3) gave the corresponding substituted cyolopropanes stereospecifically. The yields of the products were shown in the following table.
