Alkynes add to (vinylketene)tricarbonyliron(0) complexes to generate stable adducts; addition of unsymmetrical alkynes is highly regioselective and the regiochemistries of the adducts produced in these reactions were determined by X-ray crystal structure analyses of the major isomer derived from but-3-yn-2-one and (3-tert-butyl-5-phenyl-1-oxapenta-1,2,4-triene)tricarbonyliron(0), and of the structurally
炔烃添加到(乙烯基乙烯酮)三羰基铁(0)络合物中,生成稳定的加合物。添加不对称炔烃具有很高的区域选择性,并且通过X射线晶体结构分析衍生自but-3-yn-2-one和(3-叔丁基-5)的主要异构体,确定了这些反应中生成的加合物的区域化学性质。-苯基-1-氧杂戊基-1,2,4-三烯)三羰基铁(0),以及衍生自二乙基丙炔胺和(3-异丙基-5-苯基-1-氧杂戊基-1,2-4-三烯)的结构改性产物)三羰基铁(0)。
