Abstract

Abstract The regioselectivity of the hydro-alkoxycarbonylation of methyl acrylate, methacrylate, and crotonate catalyzed by [PdCl 2 L 2] complexes (L= phosphine ligands) can be largely controlled by variation of the ligands. PPh 3, promotes preferential carbonylation at the α-position, whereas with [(2, 2-dimethyl-1, 3-dioxolane-4, 5-diyl) bis- (methylene)] bis [diphenylphosphine] as ligand, the β-position is overwhelmingly ...
