The reaction of aryl iodides with ethynyl and arylethynyl, dialkyl 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 β,γ-, γ,γ-diarylallylic alcohols, and α,β-unsaturated ketones were obtained.
