The palladium(0)‐catalyzed, ligand‐controlled, regioselective addition of diaryl acetonitrile pronucleophiles to propargylic carbonates is reported. Selective formation of either terminal 1,3‐dienyl or propargylated products is proposed to arise from a change in reaction mechanism controlled by the denticity of the coordinating ligand.
据报道,钯(0)催化,配体控制,区域选择性地将二芳基乙腈前亲核试剂添加到炔丙基碳酸酯中。端基1,3-二烯基或炔丙基化产物的选择性形成被认为是由配位基团的密度控制的反应机理的变化引起的。
