A palladium-catalyzed cross-coupling reaction of sulfoxonium ylides and benzyl bromides has been developed, which has potential safety advantages over previous carbene coupling reactions using either diazo compounds or their in situ precursors. This reaction affords polysubstituted olefins, and features good substrate tolerance and is suitable for late-stage modification of biologically active molecules. Pd-carbene migratory insertion is supposed to be involved in this coupling reaction.
Preparation of new 2,3-diphenylpropenoic acid esters - Good yields even for the more hindered Z isomers

The potassium salt of E- and Z-2,3-diphenylpropenoic acids prepaxed in situ could be esterified efficiently in DMSO with the appropriate alkyl halides at room temperature. In this way 10 previously undescribed esters of these acids were synthesised and characterised. Excellent yields were observed for most of the E isomers and the more hindered Z esters were also obtained in good yields, far better than those obtained applying the classical acid-catalysed esterification reaction.
