The addition of a range of amines to vinyldiphenylphosphine oxide was examined under different reaction conditions. The methodology provides mixed phosphorus-nitrogen donor ligands R-NH(CH2CH2PPh2) 3 and R-N(CH2CH2PPh2)2 4, which could be prepared in high yields and purity in two simple steps. Labelling study revealed a non-concerted mechanism and the X-ray crystal structure of 1e is reported.
