## The 2-chloro-3-(2'~chloroalkyl)cyclopropenones 4, readily obtained by hydrolysis of the adducts of the m'chlorocyclopropenylium ion onto alkenes, thermally rearrange to propiolic acid chlorides 6. Treatment of 4 with TosOHJ+O in CH,Cl, yields the (E)-3-chloro-2-(2'-chloroalkyl)acrylic acids 9, wh

## Abstract The lithium diphenylphosphonium di(methylide) Ph~2~ P(CH~2~)~2~ Li __1__ readily attacks cyclic carbonates, carbamates, and thiocarbamates, resulting in βpseudoβacylationβ products, after a ringβopening step. Thus, new stabilized ylides are prepared, which can be used in situ as carbony
