OBSERVATIONS AND COMMENTS ON THE THERMAL BEHAVIOR OF 7-SILANORBORNADIENES

Evidence for a radical mechanism in the termal decomposition of a 7-silanorbornadiene is presented.It is demonstrated that 2-carboxy-7-silanorbornadienes undergo a formal 1,5-migration of silicon to form O-silyl enol ethers.An earlier suggested rearrangement of a 7-silanorbornadiene to a silepin or silanorcardiene is excluded.A recent report of thermal and photochemical epimerization of 7-silanorbornadienes is shown to be incorrect.
