摘要

Abstract A mixture of tris (dibenzylideneacetone) dipalladium (0)(Pd 2 dba 3) and 5-(di-tert- butylphosphino)-1′, 3′, 5′-triphenyl-1′ H-[1, 4′] bipyrazole (Bippyphos) is shown to be a robust and efficient catalyst system for the hydroxylation of structurally diverse (hetero) aryl halides under mild conditions and with broad substrate scope. Included in this reactivity survey is the successful synthesis of substituted benzofurans and related heteroatomic ...
