The reaction of aryl iodides with ethynyl and arylethynyl,dialky l carbinols in the presence of the tri- or dialkylammonium formate-palladium reagent provides a convenient route to γ,γ-diarylallylic alcohols. In the presence of arylethynyl,alkylcarbinols a lack of regioselectivity was observed and mixtures of ß,γ-, γ,γ-diarylallylic alcohols, and α,ß-unsatu rated ketones were obtained.
芳基碘化物与乙炔基和芳基乙炔基,二烷基甲醇在三甲酸铵或二烷基甲酸铵-钯试剂存在下的反应提供了一种方便的合成γ,γ-二芳基烯丙基醇的途径。在存在芳基乙炔基,烷基羰基醇的情况下,观察到区域选择性的缺乏,并且获得了ß,γ-,γ,γ-γ-二芳基烯丙基醇和α,ß-不饱和的酮的混合物。
