The reaction of (substituted) alkenylidene-hydrazinecarbothioamides with 2-(1,3-dioxo-2,3-dihydro-1H-inden-2-ylidene)propanedinitrile led to the formation of 1,3-dioxospiroindene[1,3]-thiazine and thioxoindeno[2,1-d]imidazolone derivatives in modest yields. In addition, 1,3-dihydroxyindan-2-ylidenepropanedinitrile was found. Explanations of these conversions involving nucleophilic reactions and condensations
(取代)亚烷基-肼基甲硫基酰胺与2-(1,3-二氧代-2,3-二氢-1 H-茚满-2-亚烷基)丙烷引发的反应导致形成1,3-二氧代螺螺茚[1,3]噻嗪和噻氧并茚并[2,1- d ]咪唑啉酮衍生物产量不高。另外,发现了1,3-二羟基茚满-2-亚丙基丙烷ed。这些解释涉及亲核反应和缩合。
