Participants

Reaction Steps

Diethyl 3,3-diphenylpropylbromide (43.0 g, 0.156 mol) and triethyl phosphite (51.9 g, 0.31 mol) was heated to 150° C. for 20 hours in a flask equipped with nitrogen flow through and an air condenser. Extra triethyl phosphite (20 ml) was added and heating continued to 160° C. for 3 hours. The yellow reaction solution was distilled, collecting several fractions to give the title product as a pale yellow liquid (b.p. 162-176° C. at 0.08 mbar) that crystallised on standing.
