Abstract
α, β-Dihydroxy-α, α-dianisylbutane was obtained by the reaction of p-methoxybenzoyl-ethyl carbinol and 4-methoxyphenylmagnesium bromide. By distillation under reduced pressure or treatment in 30% sulfuric acid with heating, the former gave α, α-dianisyl-β-butanone. Treatment of β-hydroxy-α, β-dianisyl-α-ethylbutane with phosphorylchloride with heating yielded 4, 4′-dimethoxy-α, β-diethylstilbene.
