Abstract

Abstract A wide variety of 1, 3-dienes have been prepared by the Heck vinylation of vinyl bromides using [Pd (η 3-C 3 H 5) Cl] 2/cis, cis, cis-1, 2, 3, 4-tetrakis [(diphenylphosphino) methyl] cyclopentane (Tedicyp) as the catalyst precursor. Both α-and β-substituted vinyl bromides undergo the Heck reaction with functionalised alkenes such as acrylates, enones, styrenes or a vinyl sulfone, and also with nonfunctionalised alkenes such as dec-1-ene, ...
