Abstract

Novel, independent syntheses of phosphacumulenes are reported for the 1‐phosphaallene 1 and the 1,3‐diphosphaallene 2 . 1 is prepared via a Wittig reaction from R PCO and Ph 3 PCPh 2 . 2 is obtained from the same educt with RP(X)SiMe 3 ; as desired, the reactions can be performed using either a two‐step (XH) or one‐step (XLi) procedure. equation image
