Abstract

The hydrocarboalkoxylation of N-vinylphthalimide catalyzed by palladium tertiary phosphine complexes occurs with high selectivity towards the linear isomer when the alc. is used also as the solvent but towards the branched isomer in the presence of an addnl. solvent. When triphenylphosphine is employed as the ligand, the yield and the regioselectivity towards the branched isomer increase with increasing pCO or decreasing concn. of the phosphine. Reaction in the presence of mol. H leads to higher yields, with minor changes in regioselectivity. High regioselectivities towards either the linear or the branched isomer are obsd. also in the presence of chiral di- or mono-phosphines, but the degree of asym. induction is very low.
