Abstract: We report a metal- and oxidant-free aromatic C-C bond cleavage in the curved corannulene skeleton. Reaction of 1-aminocorannulene with hydrazonyl chloride generates an amidrazone intermediate that undergoes facile intramolecular proton migrations and ring annulation to… read more here.

Abstract: The pioneering nickel-catalyzed cross-coupling of C-O electrophiles was unlocked by Wenkert in the 1970s; however, the transition-metal-catalyzed asymmetric activation of aromatic C-O bonds has never been reported. Herein the first enantioselective activation of an aromatic… read more here.

DOI: 10.1021/jacs.8b01658
Abstract: Aromatic C-H bond activation has attracted much attention due to its versatile applications in the synthesis of aryl-containing chemicals. The major challenge lies in the minimization of the activation barrier and maximization of the regioselectivity.… read more here.
