The geometrical isomers of 3, 3′-dimethoxy (2)-, 3, 3′-dimethyl (3)-, 3, 3′-dibromo (4)-, and 3, 3′-dinitro (5)-α, α′-dimethylstilbene were prepared from the corresponding 3-substituted acetophenones by Vargha and Kovacs's method. While the hydrazones-of 3-bromo or 3-nitroacetophenone yielded both cis- and trans-(4) or (5), respectively, as was expected, the hydrazones of 3-methoxyacetophenone gave only trans-(2) or (3), respectively. The oily products considered to be another isomers of (2) or (3) were also obtained from the reaction mixtures but attempt to isolate these compounds in pure form was abandoned owing to difficulty of purification.
