Alkene synthesis using phosphonium ylides as umpolung reagents

Alkene synthesis using phosphonium ylides as umpolung reagents

We report a transformation between a well‐known nucleophile, phosphonium ylide, and an electrophile. Subsequent ylide‐ylide coupling achieves unusual (Z )‐selectivity as compared to the conventional Wittig olefination. The synthesis of medium‐sized ring olefins has also been demonstrated, together w...
