Indenoxadiazine, indenopyrazole and spiro triazole derivatives from (substituted ylidene)-N-phenylhydrazine carbothioamides

In a multistep reaction, indeno[2,1-e][1,3,4]oxadiazine-9-one, oxoindeno[1,2-c]- pyrazolecarbothioamide, (thioxo-1,2,4-triazaspiro[4.5] decadienylidene)malononitrile and spiro-(fluorine-9,3′-[1,2,4]triazoline)- 5′-thione derivatives have been formed from a series of (substituted ylidene)-N-phenylhydrazinecarbothioamides 1a-e with (1,3-dioxo-2,3-dihydro-1H- inden-2-ylidene)propanedinitrile, 7,7′,8,8′-tetracyanoquinodimethane and (2,4,7-trinitro-9H-fluoren-9-ylidene)propanedinitrile in aerated pyridine. Rationales of these conversions involving the nucleophilic reactions, condensation, dehydrogenation and oxidation are presented.
