Formation of a benzosilacyclopentene. Formation of a silacyclopropane by intramolecular insertion of a silylcarbene
Abstract
Pyrolysis of phenyltrimethylsilyldiazomethane gave 1,1-dimethyl-2,3-benzo-1-silacyclopent-2-ene and the dimerization product of the silylcarbene, whilst photolysis in benzene, gave only the dimerization product.
