the Buchwald–Hartwig (hetero)arylation of anilines, diarylamines, and dialkylamines mediated by the expanded-ring N-heterocyclic carbene palladium complex (THP-Dipp)Pd(cinn)Cl [THP-Dipp = 1,3-bis(2,6-diisopropylphenyl)-3,4,5,6-tetrahydropyrimidin-2-ylidene; cinn = cinnamyl, 3-phenylallyl] was developed. The catalytic protocol was efficient for the coupling of amines and (hetero)aryl chlorides and bromides
苯胺、二芳胺和二烷基胺的 Buchwald-Hartwig(杂)芳基化的高效无溶剂方案,由扩环 N-杂环卡宾钯配合物 (THP-Dipp)Pd(cinn)Cl [THP-Dipp = 1,3-双(2,6-二异丙基苯基)-3,4,5,6-四氢嘧啶-2-亚基;cinn = cinnamyl, 3-phenylallyl] 被开发出来。催化方案对于胺和(杂)芳基氯化物和带有供体、受体和大取代基的溴化物的偶联是有效的。
