Novel synthesis of β-substituted β-diphenylmethylstyrenes from β-substituted β-methylstyrenes in the presence of palladium(II) acetate
Abstract
β-Substituted β-methylstyrenes react with benzene in the presence of palladium(II) acetate to produce the corresponding (E)- and/or (Z)-β-substituted β-diphenylmethylstyrenes in good yields. A mechanism involving a 2-substituted 3,3-diphenylpropene intermediate is suggested. The configurations of the products are discussed.
