Site- and Regio-selective Incorporation of Carbon Dioxide into the C(sp(2))-Si Bond of Benzosilacyclobutenes
A reaction of benzosilacyclobutenes with carbon dioxide is catalyzed by a nickel complex having an N-heterocyclic carbene ligand. Carbon dioxide inserts into the C(sp(2))-Si bond in a site-and regio-selective manner to form a carbon-carbon bond, furnishing benzoic acid derivatives.
