[Also in Divisions C3 and C4] In Example 4, bis-(1,3-cyclohexyloxy) cyclohexane is prepared by hydrogenation of m-diphenoxybenzene over a rhodium on carbon catalyst. In Example 10, cyclododecyl cyclohexane carboxylate is prepared by reacting cyclododecanol with cyclohexane carbonyl chloride. In Example 12, 1,2,3-triphenyl-2-propanol is prepared by the Grignard addition of phenylmagnesiumbromide to 1,3-diphenylacetone followed by hydrolysis. In Example 14, 1-phenylcyclododecanol is prepared by the Grignard addition of phenylmagnesiumbromide to cyclododecanone followed by hydrolysis.
