Described in this communication is a new synthesis of N ‐methyl‐4‐(vinylaryl)quinolinium salts by cyclization of the aminoketones, Ar‐CH=CH‐CO‐CH 2 ‐CH 2 ‐N(CH 3 )‐C 6 H 4 ‐X. The aminoketones were obtained by replacement of the alkyiamino group of the ketoarylidene Mannich bases with various N ‐methylarylamines. The U.V. spectra of the compounds were obtained. The photosensitivity characteristics in solution are reported. These data show the possibility of dimerization and probable trans → cis isomerization on exposure to visible and ultraviolet light.
