Abstract: Rhodium-catalyzed hydroformylation of vinyl acetate with the use of diphosphine ligands was studied. A high regioselectivity (branched:linear of 99:1) and activity (TOF: 4000 h−1) under optimum conditions were achieved by using a 2,2’-bis(diphenylphosphino methyl)-1,1’-biphenyl ligand. The high turnover number (9200) obtained under mild conditions and stability of the catalyst indicates that it would be useful for industrial vinyl acetate hydroformylation.

Key words: vinyl acetate, hydroformylation, regioselectivity, diphosphine ligand, 2-acetoxypropanal
