DOI: 10.1021/acs.orglett.5c02217

Abstract: Herein, we describe a photocatalytic strategy for decyanative hydrofunctionalization of styrenes with α-heteroatom-substituted acetonitriles. This strategy facilitates the generation of α-heteroatom methyl radicals from acetonitriles through cyano group transfer (CGT) enabled by amine-ligated boryl radicals.… read more here.

DOI: 10.1021/acs.orglett.7b03201

Abstract: A new protocol for radical transformations of thioamides promoted by Lewis base-boryl radicals is reported. The desulfurizative reduction to access organic amines was enabled utilizing 4-dimethylaminopyridine-BH3 as the boryl radical precursor and PhSH as the… read more here.

DOI: 10.1021/jacs.2c10444

Abstract: Herein, we present a comprehensive study on the use of N-heterocyclic carbene (NHC)-ligated boryl radicals to enable C(sp3)–C(sp3) bond formation under visible-light irradiation via Halogen-Atom Transfer (XAT). The methodology relies on the use of an… read more here.

DOI: 10.1021/jacs.5c03864

Abstract: Organic free radicals are commonly perceived to be highly reactive species with short lifetimes, yet there are many examples that defy this convention by displaying remarkable stability. Although these persistent radicals can be relatively unreactive… read more here.

DOI: 10.1055/a-2464-8904

Abstract: Alkynylboron compounds are important scaffolds with broad applicability in organic synthesis. In contrast to polar or metal-catalyzed processes, here a radical approach is employed for the addition of nucleophilic boryl radicals to electrophilic SOMOphiles for… read more here.
