(1E,3E,5Z)-1,6-Dibromohexa-1,3,5-triene: regio- and stereocontrolled mono pallado-catalysed cross-coupling reactions

Abstract : We describe the regio- and stereocontrolled synthesis of (Z,E,E)-α-bromo-ω-substituted hexatrienes. The synthesis is based on a mono pallado-catalysed cross-coupling reaction between (1E,3E,5Z) isomer of 1,6-dibromohexa-1,3,5-triene and various organozinc reagents. Mono pallado-catalysed cross-coupling reaction from (1E,3E,5Z)-1,6-dibromohexa-1,3,5-triene and various organozinc reagents has given regio- and stereoselectively conjugated (Z,E,E)-α-bromo-ω-substituted hexatrienes.
