The reactivity of primary phosphine-boranes RPH2'BH 3 (R = Ph and Me) towards CH2=CHCO2Me and CH2=CHP(O)(OMe)2 is discussed. Hydrophosphination is the major process. The presence of the free phosphine (0-20%) in the crude media indicates that a competitive hydroboration reaction also occurs. The P-H
