The phase transfer catalytic (PTC) bis-Wittig reaction between substitutedbenzaldehyde and 1,2- and 1,3-bisylides in the presence of K2Co3 was discussed.
a-Phenylthio-a, b-unsaturated esters 6 were synthesized by Witting reaction of 3, which were prepared by a phenylsulfenyllation-trans-ylidation reaction.
