A Photocatalytic C(sp)–B Bond Formation Employing SOMOphilic Alkynyl Sulfones and Nucleophilic Boryl Radicals

Year: 2024

Type: article

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 the construction of the C(sp)–B bond. The reaction renders the corresponding alkynylated amine boranes with broad functional group compatibility. In addition, theoretical studies have been carried out by means of DFT to understand the reactivity and selectivity of the addition process.
