Versuchsvorschrift

A mixture of 40.8 g (0.155 mol) of 3,3-diphenylallyl chloride (11a) and 94.48 g (0.569 mol) of triethyl phosphite was stirred with refluxing for 24 hours. The disappearance of the 3,3-diphenylallyl chloride (11a) was ascertained, before the reaction was terminated. After cooling, the reaction mixture was distilled with a Claisen flask equipped with a vigreux to obtain 55.39 g of the target compound.
