Cyclocondensation of α,β-unsaturated aromatic ketones V and VIII with quaternary pyridinium salts VI in the presence of ammonium acetate gave 2,4,6-triarylpyridines I, aryl-substituted diaza-p-terphenyls IIa,b, diaza-p-quaterphenyls IIc,d and diaza-p-quinquephenyls IIe,f.All the new polyphenylene compounds exhibit characteristic luminiscence in the visible spectral region.

A wide variety of 2,4,6-triaryl-substituted pyridines have been synthesized by the interaction of aroylmethylenepicolinium ylides with different α,β-unsaturated ketones.The structural assignments were based on microanalytical and spectral data.
Studies on Cycloimmonium Ylids: Synthesis of Some 2,4,6-Triarylpyridines via Isoquinolinium Ylids

Aroylmethylene-isoquinolinium ylids on reaction with substituted benzylidenacetophenones in gl. acetic acid containing ammonium acetate afford 2,4,6-triarylpyridines (4a-j).The reaction seems to proceed via the intermediacy of pentane-1,5-dionylisoquinoli
