Abstract
The method of preparing 3, 4-diphenylhexane compounds by the condensation of alkylbuten-(2)-ol-(4) and benzene derivatives, with conc. sulfuric acid as a condensation agent, was designated the allylalcohol method. Distinguishing the two methods available, the one-step method was designated as A method, and the stepwise synthesis as B method. Asymmetric compounds possessing different alkyl groups, of the type Ar-CH(R)-CH(R′ differ), such as 3, 4-(p, p′-dimethoxydiphenyl)-pentane, -heptane, and -octane were prepared by the two methods, A and B. It was confirmed that these compounds had not undergone allyl rearrangement by the direct comparison with the same compounds prepared by still another method.
