carbene C,S palladium(II) π-allyl complexes were successfully developed and characterized. Structural analyses of these complexes revealed that the organopalladium chelates adopt a skew-envelope conformation with a trans disposition of the substituents on the metal chelate rings. Utilizing these C,S palladium(II) π-allyl complexes as catalysts, a catalytic system for the allylic amination reaction has
成功开发并表征了一系列五元N-杂环卡宾C,S钯(II)π-烯丙基配合物。对这些配合物的结构分析表明,有机钯螯合物采用偏斜包络构象,且金属螯合物环上的取代基发生转位。利用这些C,S钯(II)π-烯丙基络合物作为催化剂,已经开发出用于烯丙基胺化反应的催化体系。胺与不对称取代的烯丙基碳酸酯之间的一系列C–N键形成可通过区域选择性方式的复杂(±)-9高效催化。
