The reaction of tropone tosylhydrazone sodium salt with 3- or 5-methoxycarbonyl-2-pyrones afforded benzotropilidene derivatives. These products are considered to be formed via addition reactions of the 2-pyrone derivatives with 1,2,4,6-cycloheptatetraene derived from cycloheptatrienylidene, which is the initial product of the decomposition of tropone tosylhydrazone sodium salt.
