O,O′-Bistributyltin benzopinacolate (1,1,2,2-tetraphenylethane-1,2-bisolate) as thermal source of tributylstannyl radicals
Abstract
The previously unknown bistributyltin benzopinacolate was prepared by photolysis of benzophenone in the presence of bistributyltin and used for thermal formation of aryl radicals that undergo subsequent intramolecular addition to an imne bond in an ortho-substituent.
