摘要

Ring cleavage of the N-oxides of S-methylazacycloalkanes by a thermal elimination reaction does not occur when the ring is sixmembered and becomes progressively easier as the ring size is increased from seven to eight atoms. X-Methylpiperidine oxide gave IIO product from a cis@-elimination reaction, while pyrolysis of the homologous N- methylhexamethyleneimine and N-methylheptamethyle~ ieimine oxides led to the ...
