Abstract: Herein, we report a distinctive photoredox/copper dual-catalyzed esterification of benzylic C-H bonds through the combination of photoredox-mediated hydrogen atom transfer and Cu(II)-mediated radical-polar crossover. This methodology demonstrates a high functional group tolerance (>40 examples) and… read more here.

DOI: 10.1021/acs.orglett.3c01147
Abstract: An efficient photoredox/nickel dual-catalyzed coupling of allyl trifluoroborates with aryl halides has been developed, which provides an attractive route to diverse-substituted allylic benzenes. The method offers several advantages, such as high efficiency and regioselectivity, mild… read more here.

DOI: 10.1039/d2cc05934g
Abstract: Radical defluorinative functionalization of α-trifluoromethyl styrenes represents an effective way toward gem-difluoroalkenes. There are general interests in developing novel synthetic protocols for defluorinative functionalization with various types of radicals. However, reports on the preparation of… read more here.
