Abstract: Spiro [2.3] hexane-4-methanol (2) was formed upon prolonged treatment of methyl 4-chlorobicyclo-[2.2. 0] hexane-l-carboxylate (1) with lithium aluminum hydride, and the rearrangement of the p-toluenesulfonate ester 4 of this alcohol was studied. The rate of this rearrangement in acetic acid buffered with sodium acetate was the same as that of cyclobutylmethyl p-toluenesulfonate, indicating that the cyclopropyl ring had no effect on ...
