The preparation of a 1,3-bis(2,6-terphenyl)imidazol-2-ylidene, IDitop (Ditop=2,6-bis(4-tolyl)phenyl-) is reported. Several late transition metal complexes as well as the selenium adduct of IDitop were prepared to study and compare the stereoelectronic properties of IDitop to other well-known N-heterocyclic carbenes (NHCs). A study of the steric character of IDitop taken from crystal structure data
报道了 1,3-双(2,6-三联苯基)咪唑-2-亚基,IDitop (Ditop=2,6-双(4-甲苯基)苯基-)的制备。制备了几种晚期过渡金属配合物以及 IDitop 的硒加合物,以研究和比较 IDitop 与其他众所周知的 N-杂环卡宾 (NHC) 的立体电子特性。从配合物和加合物的晶体结构数据中获取的对 IDitop 空间特性的研究显示出高度的灵活性。初步应用于具有挑战性的 Suzuki 偶联反应。
