Reactions between CS2 and the exocyclic amino groups of 2-aminobenzothiazoles gave series of molecules bearing thiourea, isothiourea, dithiocarbamate, dithiocarboimine, dimethyldithiocarbamate, methyldithiocarbamate, S-CH3 and O-alkyl thiocarbamic ester, and guanidine groups. Preferred tautomers and conformers were determined. Most compounds present coordinative bonds between the endocyclic sulfur
CS2 与 2-氨基苯并噻唑的环外氨基之间的反应产生了一系列带有硫脲、异硫脲、二硫代氨基甲酸酯、二硫代碳亚胺、二甲基二硫代氨基甲酸酯、甲基二硫代氨基甲酸酯、S-CH3 和 O-烷基硫代氨基甲酸酯和胍基团的分子。确定了优选的互变异构体和构象异构体。大多数化合物在环内硫原子(其作用类似于路易斯酸)与氧、氮和硫(充当碱)之间存在配位键。讨论了一种含有 T 形高价硫原子并显示“单键-无键共振”的新型二苯并噻唑基四氮杂硫戊烯。报告了十一种化合物的 X 射线结构。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2004)
