The saturated α-aminophosphine ligands containing a secondary amine function Ph2PCH(R′)NHR″ establish a solution equilibrium with Ph2PH and R′CH2NR″ and are stabilized by electron-withdrawing substituents R′ and R″ and by coordination of the phosphorous donor to Cu(I).

Addition of a secondary phosphine-borane adduct to imines was examined in order to improve the synthesis of mono-N-substituted-alpha-aminophosphines. The reaction demonstrates, for the first time, successful addition of a phosphine-borane to a multiple carbon-nitrogen bond. The process tolerates a range of substituents on the imine and results in an efficient formation of a borane-protected alpha-aminophosphine, Borane protects the aminophosphine and improves the reliability of the Mannich-like phosphine addition to imines.
