Abstract

Abstract : An efficient visible light photocatalytic strategy to synthesize Z -arylvinyl halides from E -arylvinyl acids using N -halosuccinimide through a sequential halodecarboxylation/photoisomerization with up to >99/1 Z / E ratio and 86% yield under mild reaction conditions. Abstract : An efficient visible light photocatalytic strategy to synthesize thermodynamically less stable Z -arylvinyl halides (with up to >99/1 Z / E ratio and 86% yield) was developed. The reaction combined base-mediated halodecarboxylation of E -arylvinyl acids with N -halosuccinimide and visible light Ir-photocatalyzed isomerization of E -arylvinyl halides in a one pot sequential catalytic process.
