An imidazolium-based organopalladium-functionalized heterogeneous catalyst is prepared by the immobilization of bis[(diphenylphosphino) ethyltriethoxysilane)]palladium dichloride onto an imidazolium-based organic-inorganic hybrid silica. It enables the one-pot tandem Suzuki cross coupling-reduction of haloacetophenones and arylboronic acids, providing a range of biaryl alcohols with high yields. The superior catalytic performance is attributed to the nature of the uniformly distributive, well-defined confined organopalladium active species within its imidazolium-based silicate network.
