There has been many reports of the generation and their reactions of silabenzene intermediate from the readily available allyl or chloro precursors. The intramolecular reacton of 1-methyl-2,3,4,5-tetraphenylsilacyclopentadienylmethlene to give silatoluene was reported by Anbo and Sekiguchi.
West and coworkers reported the existence of the intermediacy of hexamethyl-1,4-disilabenzene. In 1978, Barton and Burns confirmed the first unambiguous generation and trapping of the silatoluene formed via a thermally induced retroene elimination of propene from the 1-allyl-1-methyl-1-silacy-clohexa-2,4-diene. There is precedent for the unsuccessful approach to produce 2-silanaphthalene intermediate from the thermolysis or photolysis of silyl diazo compound 1 in the presence of methanol.
