Secondary phosphines 1-3 react readily with N-vinylpyrroles 4 and 5 under radical initiation to give regiospecifically anti-Markovnikov adducts, diorganyl-2-(1-pyrrolyl)ethylphosphines 6a-d, highly reactive building blocks for organic synthesis, in 88-91% yields.

Addition of a secondary phosphine±borane adduct to imines was examined in order to improve the synthesis of mono-N-substituted-a-aminophosphines. The reaction demonstrates, for the ®rst time, successful addition of a phosphine±borane to a multiple carbon±nitrogen bond. The process tolerates a range
