Stereospecific radical–radical-anion combination in the reductive aminoalkylation of anthracene
Abstract
The aminoalkylation of lithium dihydroanthracenylide occurs with complete retention of the configuration and the CαCN bond-breaking involves sp3–sp2 hybridisation change; the most consistent explanation of these results is the directing effect of LiCN on the radical–radical-anion combination.
