1,8-Diazabicyclo(5.4.0)undec-7-ene → 1-(2-Benzyloxyphenyl)-4-(2-chlorophenyl)butadiene

Participants

Reaction Steps

Then, following a procedure similar to that described in the first part of Preparation 3, the whole of this 3-(2-chlorophenyl)-2-propenal was reacted with 7.97 g of 2-benzyloxybenzyltriphenylphosphonium chloride (prepared as described in Preparation 1) and 3.35 g of 1,8-diazabicyclo[5,4,0]undec-7-ene. The resulting crude product was purified as described in the first part of Preparation 3, to give 4.57 g (yield 90%) of 1-(2-benzyloxyphenyl)-4-(2-chlorophenyl)butadiene as an oil.
