Ni-Catalyzed Stannylation of Aryl Esters via C−O Bond Cleavage

A Ni-catalyzed stannylation of aryl esters with air- and moisture-insensitive silylstannyl reagents via C(sp2) −O cleavage is described. This protocol is characterized by its wide scope, including challenging combinations, thus enabling access to versatile building blocks and orthogonal C−heteroatom bond formations.
