ABSTRACT
Aluminum chloride has been found to be a highly efficient catalyst for the aldol condensation of aldehydes and cycloketones in poly(ethylene)glycol 400 at room temperature. The reaction is very fast, clean and environmentally benign for the synthesis of a variety of α,α'-bis(substituted-benzylidene) cycloalkanones.
Keywords: Aluminum chloride, poly(ethylene)glycol, α,α'-bis(substituted-benzylidene) cycloalkanones, aldol condensation
