A method for the introduction of various substituents at the 4 and 8 positions of 2,10-di-tert-butyldipyrido[1,2-c;2',1'-e]imidazolium salts, is described. The new imidazolium salts bearing substituents (R' = Cl, SPh) at the 4 and 8 positions are synthesized in three-step procedures, and carbenes generated from the imidazolium salts can be used to give the corresponding rhodium complexes. The role of the 4,8-substituents can be either bystanders or coordinating ligands according to the nature of the metal moiety.
描述了一种在2,10-二叔丁基二吡啶并[1,2-c;2',1'-e]咪唑鎓盐的4位和8位引入各种取代基的方法。在4位和8位带有取代基(R' = Cl,SPh)的新型咪唑鎓盐通过三步程序合成,并且由咪唑鎓盐产生的卡宾可用于制备相应的铑配合物。根据金属部分的性质,4,8-取代基的作用可以是旁观者或配位配体。
