Cobalt-catalyzed branched-selective addition of aromatic ketimines to styrenes under room-temperature conditions

Dong, Jinghua,Lee, Pin-Sheng,Yoshikai, Naohiko

supporting information, p. 1140 - 1142 (2013/10/22)

An improved cobalt-based catalytic system has been developed for the branched-selective addition of aromatic ketimines to styrenes. With an appropriate combination of triarylphosphine and the Grignard reagent, the reaction takes place smoothly at room temperature to afford 1,1-diarylethane derivatives with high regioselectivity.
