This allows Shell to run their hydroformylation plant under milder pressures and temperatures: 180-200° C. and 60-70 bar. The phosphine ligand increased the aldehyde L:B selectivity to 8:1, which is very desirable for Shell's market. WebThe invention relates to an improved process for the preparation of an advanced synthetic intermediate of ACE inhibitors. In one aspect, the present invention is based on a novel process for the preparation of an aldehyde of formula (I), wherein (N)PrG is a protected amino group, R is an alkyl or aralkyl group and X1-4 are each independently H or a non … daryl hall previously worked with
