Abstract: Chemoselective iron-catalyzed dehydrogenative cross-coupling using 2-acylimidazoles is described. The addition of a phosphine oxide ligand substantially facilitated the generation of tert-butoxy radicals from di-tert-butyl peroxide, allowing for efficient benzylic C–H bond cleavage under mild conditions.… read more here.

DOI: 10.1021/jacs.9b06204
Abstract: A proof-of-principle study of cascade dehydrogenative cross-coupling of carboranyl carboxylic acid with readily available benzamide has been achieved, resulting in the facile synthesis of previously inaccessible carborano-isoquinolinone derivatives in a simple one-pot process, in which… read more here.

Abstract: Ir-Catalyzed -COOH directed site-selective B-H/C-H dehydrogenative cross-coupling of o-carborane with thiophenes has been achieved for the first time. Without any pre-functionalization, carboranyl carboxylic acids and thiophenes can serve as suitable coupling partners, resulting in the… read more here.

DOI: 10.1039/d2cc02852b
Abstract: A unique approach to vertex-selective catalytic B-H amination at either the B(3)- or B(4)-position in o-carboranes has been developed. Using different transition metal catalysts, dehydrogenative BH/NH cross-coupling of o-carboranes and free amines has been achieved,… read more here.
