ABSTRACT Two C, N-linked dimeric 1, 2-dihydro-2, 2, 4-trimethylquinolines, namely 6- chloro-1-(6-chloro-1, 2-dihydro-2, 2, 4-trimethylquinolin-8-yl)-1, 2-dihydro-2, 2, 4- trimethylquinoline (3a) and 6-ethoxy-1-(6-ethoxy-1, 2-dihydro-2, 2, 4-trimethylquinolin-8-yl)- 1, 2-dihydro-2, 2, 4-trimethylquinoline (3b), have been prepared through a silver-catalyzed dimerization of their corresponding monomers. The effect of different silver salts on the ...
