Simple and efficient diphosphinite ligands were evaluated in rhodium catalyzed hydroformylation of vinyl acetate. The effect of various reaction variables like temperature, pressure, substrate/Rh ratio, P/Rh ratio, solvents, time and different types of phosphorous ligands were studied. The diphosphinite ligand exhibited a considerable impact on the hydroformylation of vinyl esters and provided good turnover number (up to 10,000) with excellent regioselectivity (99%) to branched aldehyde. Wide range of vinyl esters including long chain aliphatic vinyl esters (up to C18) were well tolerated to provide good to excellent yield of desired product. (C) 2013 Elsevier B.V.

Synthesis of α-Amidoketones from Vinyl Esters via a Catalytic/Thermal Cascade Reaction
straightforward, modular, and atom-efficient method is reported for the synthesis of α-amidoketones from vinyl esters via a cascade reaction including hydroformylation, condensation with a primary amine, and a rearrangement step giving water as the only byproduct. The reaction sequence can be performed in one pot or as a three-step procedure. The synthetic applicability is demonstrated by the preparation of different
