A new solvent system for recycling catalysts for chelation-assisted hydroacylation of olefins with primary alcohols.
A new method to separate and reuse the catalyst system consisting of a rhodium complex and 2-aminopyridines for chelation-assisted hydroacylation was achieved using phenol and 4,4'-dipyridyl as the reaction medium, and 4-diphenylphosphinobenzoic acid as a ligand.
