is reacted with an alkali metal in an inert solvent, the phenyl group is split off yielding the corresponding alkali heterocyclopentadienide. Hydrolysis of the alkali phosphacyclopentadienides gave the first P-unsubstituted phospholes (7a, 7b, 10). Similarly, this method allows the dephenylation of N-phenyl substituted pyrroles. Reaction of the alkali phospholides with alkyl halides offers a convenient
