Diphenylphosphine → Trimethylsilylethyl Diphenyl Phosphine

Participants

Reaction Steps

A magnetically stirred mixture of 46.5 g (0.25 mole) diphenyl phosphine and 25 g (0.25 mole) of vinyl trimethyl silane, in a closed cylindrical quartz tube, was irradiated from about 3 cm distance with two 75 Watt Hanau tube immersion lamps, with a wide spectrum of ultraviolet irradiation, in a 15° C. water bath for 26 hours. A proton magnetic resonance spectrum of a sample of the resulting mixture exhibited no significant peaks in the vinyl region indicating a substantially complete addition.
