Sonochemical dehalogenation of 2,4-dichloroquinoline is very facile.However, with 5,7-dimethoxy-2,4-dichloroquinoline the reaction proceeds stepwise to provide the title dimethoxyquinolines which cannot be prepared via the Skraup reaction.The 13C NMR chemical shift assignments for 5,8-dimethoxyquinoline are presented.These were made by utilising the coupling connectivities from the bridgehead carbons in the 2D COLOC spectrum. - Keywords.Sonochemistry; Quinolines; 13C NMR Spectroscopy; 2D COLOC spectrum.
