Abstract
The present invention provides a novel eco-friendly multi-functional catalyst system useful to obtain C2(n+1) aldol-derivative from Cn-alkenes where n ranges from 2 to 10 in a single step under hydroformylation reaction conditions and adol formation conditions.
Claims36
Process for preparing an aldol derivative from the corresponding alkene in a single step using a eco-friendly multi-functional catalyst system, the process comprising:
- (a) contacting carbon monoxide, hydrogen and an alkene with a catalyst system consisting of a metal complex comprising hydridocarbonyltris(triphenylphosphine) rhodium(I), and a solid base, in a solvent under hydroformylation and subsequently aldol condensation conditions to obtain a product stream;
- (b) cooling the product stream obtained in step (a) and separating aldol derivative so obtained.
