(β-Trimethylstannyl)alkyldiphenylphosphines can be readily prepared by addition of diphenylphosphine to the corresponding vinyltrimethyltin Me3SnCR=CH2 under free radical conditions.In contrast, free radical hydrostannation of the corresponding phosphines Ph2PCR=CH2 is a more complex process, and is apparently of little synthetic value.The title compound can be easily oxidised by potassium permanganate to give the corresponding phosphine oxides in good yields.Hydrostannation of model alkynyldiphenylphosphines (RC<*>CPPh2, R=H, Me3Sn) occurs regiospecifically.
