FACILE FORMYLOLEFINATION OF ALDEHYDES BY MEANS OF ARSONIUM SALT
Huang, Yaozeng,Shi, Lilan,Yang, Jianhua
, p. 6447 - 6448 (1985)
A facile formylolefination of a variety of aldehydes was achieved by using formylmethyltriphenylarsonium bromide with K2CO3 (trace H2O) at room temperature to give highly stereoselectively (E) α,β-unsaturated aldehydes in excellent yields.
