Rhodium(I)-Catalyzed Synthesis of Aryltriethoxysilanes from Arenediazonium Tosylate Salts with Triethoxysilane

摘要

An efficient method for the preparation of aryltriethoxysilanes from arenediazonium tosylate salts has been developed, which expands the substrates of rhodium-catalyzed silylation from iodides, bromides, and triflates to diazonium salts. A new method for hydrodediazoniation has also been explored.
