3H-1,2-Dithiolo[3,4-b]pyridine-3-thione (10) reacts with primary alkylamines to give 1,2-dihydro-2-thioxo-3-pyridinecarbothioamides 11a-g and two minor products. Isothiazolo[5,4-b]pyridine-3(2H)-thiones 12a-g and 3-imino-3H-1,2-dithiolo[3,4-b]pyridines 13a-g were isolated and characterized. Further investigations allowed the synthesis of 12 and 13 in good yield.
3 H -1,2-二硫代[3,4- b ]吡啶-3-硫酮(10)与伯烷基胺反应,得到1,2-二氢-2-硫代-3-吡啶吡啶碳硫酰胺11a-g和两种次要产物。分离并表征了异噻唑并[5,4 - b ]吡啶-3(2 H)-硫酮12a-g和3-亚氨基-3 H -1,2-二硫代[3,4- b ]吡啶13a-g。进一步的研究允许以高产率合成12和13。
