Abstract
Tributylvinylphosphonium bromide has been prepared by sodium carbonate dehydrobromination of the 2-bromoethyl salt resultant from the reaction of tributylphosphine and dibromoethane. Tributylvinylphosphonium chloride was prepared from the bromide by ion exchange. Triethylvinylphosphonium bromide, tricyclohexylvinylphosphonium bromide, and dimethylphenylvinylphosphonium bromide were prepared by sodium carbonate treatment of the acetate resulting from acetic anhydride acetylation of the salt formed from the reaction of ethylenebromohydrin and the corresponding phosphine. An attempt to prepare a vinylphosphonium salt directly by heating vinyl bromide and tributylphosphine at 160°C. in an autoclave gave no isolable product; however, infrared evidence indicated the possible presence of the expected vinylphosphonium salt.
