Reaction of 4-substituted thiosemicarbazides with (2,4,7-trinitro-9H- fluoren-9-ylidene)propanedinitrile

4-Substituted thiosemicarbazides 4a-c reacted with (2,4,7-trinitro-9H- fluoren-9-ylidene)-propanedinitrile (2) in pyridine with admission of air to form spiro[fluorene-9,3'-(1,2,4-triazole)]derivatives 5a-c and (4-substituted thiosemicarbazono)propanedinitriles 6a-c in modest yields. 2,4,7-Trinitro-9- fluorenone (8) as well as one reduction product thereof and of 2, namely compounds 9 and 10, respectively are also found. A rationale for the conversions observed is presented.

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.

A Novel Reaction of (2,4,7-Trinito-9H-fluoren-9-ylidene)-propanedinitrile with N-Arylisoindolines

N-Arylisoindolines 1a-c reacted with (2,4,7-trinitro-9H-fluoren-9-ylidene)propanedinitrile (A) in pyridine with admission of air via a net α-H-atom abstraction and formation of [3-(2-aryl-3-arylimino-2,3-dihydro- 1H-isoindol-1-ylidene)-2-aryl-2,3-dihydro-1H-isoindol-1-ylidene] propanedinitriles 2a-c, N-[2-aryl-3-(2-aryl-3-arylimino-2,3-dihydro-1H-isoindolyl-1-idene)-2,3-dihydro- 1H-isoindol-1-ylidene]arenamines 3a,b, N,N-[2-aryl-1H-isoindole-1,3(2H)-diylidene]bisarenamines 4a,b and N-arylphthalimides 5a-c in moderate yields. 2,4,7-Trinitro-9-fluorenone as well as one reduction product each of the latter and of A, namely compounds 6 and 7, respectively, are also found. The structure of 2b has been unambiguously confirmed by an X-ray crystal structure analysis. A rationale for the conversions observed is presented. These involve dehydrogenation and oxidative couplings of 1a-c as well as transfer of N-aryl fragment from 1a-c to intermediate products.
