ABSTRACT: 1-Phenyl phospholes react with t-BuLi to yield 1-tertiobutyl phospholes. Two new phospholes are thus prepared. Trifluoroacetic acid converts phospholes into the corresponding 3-phospholene oxides and its reaction with monomeric phosphole sulfides is also investigated. Similarly benzoyl chloride yields the 2-benzoyl-3-phospholene derivatives, but an unusual rearrangement sometimes take place and 2-phenyl-2-hydroxy- ...
