• 論文の詳細を見る

• The reaction of α- or β-methylstyrene with phenylpalladium chloride in aqueous acetone were studied. From <I>cis</I>- or <I>trans</I>-β-methylstyrene, a mixture of <I>erythro</I> and <I>threo</I> isomers of hydroxyphenylation products PhMeCHCHOHPh (VIa, VIb) and chlorophenylation products PhMeCHCHClPh (IVa, IVb) were obtained accompanying the phenylated olefins (I, II, and III). The main reaction product was the tertiary alcohol PhCH<SUB>2</SUB>C(OH)MePh (V). The reaction of α-methylstyrene with phenylpalladium chloride gave V exclusively. Phenylpalladium acetate and phenylpalladium bromide were used as phenylating agents. The yields of hydroxyphenylation products are in decreasing order: chloride>bromide>acetate.
