The results of a systematic variation of achiral monodentate ligands used for the Pd-catalyzed alkylation of crotyl and 3-buten-2-yl acetates and carbonates are presented. A significant degree of retention of regiochemistry and stereochemistry was observed for these substrates, especially for nonracemic 3-buten-2-yl ethyl carbonate with PCy x Ph 3 - x and carbene ligands.
