Preparation of Allyldibromophosphine and Allyltrifluorophosphorane.

摘要

The reaction of allyldifluorophosphine with HBr has been studied. The products characterized by mass, ir, and NMR spectroscopy and by analysis--allyltrifluorophosphorane, F3PHCH2CHCH2, and allyldibromophosphine, Br2PCH2CHCH2--are consistent with initial addition of HBr to trivalent phosphorus followed by disproportionation through successive loss of HF and addition of more HBr.
