Abstract
Abstract The reaction of p-bromobenzaldehyde (1) with α-ethoxycrotyltributyltin (2) has proved amenable to control in terms of chemo, regio and stereochemistry, using appropriate experimental conditions, namely Pd(PPh 3 ) 4 catalysis, BF 3 .Et 2 O catalysis or simple heating. In the latter case, a dramatic kinetic effect has been observed: 2E has been proved to be much more reactive (and much more stereoselective) than 2Z .
