Abstract

Flash vacuum pyrolysis of 3-aroylcinnolines 3 at 900° C and 0.02 Torr yielded phenanthrene and arylacetylene derivatives as the major products beside anthracene and diarylacetylene derivatives as minor products. Also, FVP of 3-(2-thienoyl)-cinnoline gave three isomeric naphthothiophenes, phenyl-2-thienylacetylene and phenylacetylene. On the other hand, 3- (2-furoyl)-cinoline gave dibenzofuran as a major product besides naphtho [1, 2-b] furan ...
