Abstract
A very simple and efficient procedure is reported for the synthesis of 1,3-diarylimidazolinium chlorides by cyclization of N,N′-diarylethylenediamines dihydrochlorides with triethyl orthoformate under microwave irradiation. Key words
amines - cyclizations - heterocycles - imidazolinium salts - ligands
