title: Mesityllithium and p-(dimethylamino)phenyllithium for the selective alternate trilithiation of the hexaphenylbenzene framework.
abstract: We report mesityllithium and p-(dimethylamino)phenyllithium as new valuable lithiating reagents, which realize Br/Li exchange reaction of bromoarenes at relatively high temperature in THF. With these reagents, we established the general and practical protocols for the selective alternate trilithiation of the hexaphenylbenzene framework.
