The Products of the Cyclizing Dehydration of 1-Beta-Phenylethylcyclohexanol-1 and the Synthesis of Spirocyclohexane-1,1-Indanone-3
(1) Spirocyclohexane-1,1-indanone (VI) has been found among the oxidation products of the hydrocarbon mixture which results when 1-beta-phenylethyl-cyclohexanol-1 is dehydrated, or when 1-beta-phenyl-ethylcyclohexene is cyclized by aluminum trichloride, and its constitution has been proved by synthesis. (2) Its oxime melts at 137-137.8 degrees (corr.). The oxime of m.p. 187.5 degrees, reported by Cook et al. therefore must be derived from some other ketone, perhaps the trans-ketooctahydrophenanthrene, since we were unable to isolate any oxime of m.p. 177 degrees, the figure which they reported for this compound.
