## Abstract The reaction of nucleophilic phosphacumulene and phosphallene ylides with different chromenone derivatives was investigated. Heterocycles and carbocycles of various ring sizes and heteroatom patterns such as pyrano‐, oxaphosphino‐, cyclopenta‐, phosphoranylidene cyclobutane‐, and phosph

Active vinylidenetriphenylphosphoranes are nucleophilic reagents which can be considered as versatile synthons for the synthesis of new heterocycles. The active phosphacumulene ylides, namely N-phenylimino-2a, 2-oxo-2b or 2-thioxovinylidenetriphenylphosphoranes (2c), react with benzil-(1a,b), o-naph
