Ligand-controlled regioselective palladium-catalyzed decarboxylative hydrogenolysis of propargylic formates is described. A wide range of allenes and alkynes were obtained by using either 1,2-diphenylphosphinoethane (DPPE) or 1,6-bisdiphenylphosphinohexane (DPPH) as a catalyst ligand.
描述了配体控制的区域选择性钯催化的炔丙基甲酸酯的脱羧氢解。通过使用1,2-二苯基膦基乙烷(DPPE)或1,6-双二苯基膦基己烷(DPPH)作为催化剂配体,可以获得广泛的丙二烯和炔烃。
