AMOOZADEH, Ali; RAHMANI, Salman and NEMATI, Firouzeh. Poly(ethylene)glycol/AlCl3 as a green and reusable system in the synthesis of α ,'α-bis(substituted-benzylidene) cycloalkanones. S.Afr.j.chem. (Online) [online]. 2010, vol.63, pp.72-74. ISSN 1996-840X.
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-bis(substituted-benzylidene) cycloalkanones; aldol condensation.
