Abstract Previously unknown 1-[2-aryl (quinolin-2-yl) ethenyl]-3-[aryl (quinolin-2-yl)] benzo [f] quinolines and 3-aryl-1-(2-arylethenyl)-4, 7-phenanthrolines were synthesized by reactions of 1-methylbenzo [f] quinolines and 1-methyl-4, 7-phenanthrolines with substituted N- benzylideneanilines and N-(quinolin-2-ylmethylidene) aniline on heating in dimethylformamide in the presence of potassium hydroxide.
