## 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
