From a series of N,Nâ²-disubstituted-1,1â²-binaphthyl-2,2â²-diamines, several group 3 metal complexes were synthesized via an in situ procedure. These chiral complexes were subsequently applied to catalysis of intramolecular alkene hydroamination. Significant structureâactivity relationships were observed, most notably a reversal of stereoselectivity for cyclopentylversusdiphenylmethyl substituents.
通过一种原位程序,从一系列 N,Nâ²-二取代-1,1â²-联
萘-2,2â²-二胺中合成了几种第 3 族
金属配合物。这些手性配合物随后被用于催化分子内的烯烃加氢反应。观察到了显著的结构与活性关系,最明显的是环戊基与二苯基甲基取代基的立体选择性发生了逆转。
