Pyrolysis of bis(trimethylsilyl)phenylmethanol gave (trimethylsilyl)phenylcarbene by the elimination of trimethylsilanol and the products were compared with those of (trimethylsilyl)phenyldiazomethane.Alkylsilylcarbenes obtained from the pyrolyses of 1,1-bis(trimethylsilyl)-1-alkanols afforded vinyltrimethylsilanes in high yields. (Trimethylsilyl)phenylmethanols were found to be excellent precursors of phenylcarbenes and their intramolecular reactions were also studied.
