The reaction of dimethyl N-phenylsulfonylcarbonimidodithioates (1) with diamines gave three different types of products due to changes in the molar ratio of the starting materials. From aliphatic diamines heterocyclic 1 : 1 and acyclic 2 : 1 reaction products were obtained. In order to prepare macrocycles, the reaction of 1 with 1,10-diamino-4,7-dioxadecane (10) was carried out. 1,1′-(4,7-Dioxadecamethylene)bis(2-methyl-3-phenylsulfonylisothiourea)s (11) and 9-phenylsulfonylimino-1,4-dioxa-8,10-diazacyclotridecanes were obtained by 2 : 1- and 1 : 2-mixed reactions of 1 with 10, respectively. The 2 : 2 reaction products, 9,22-bis(phenylsulfonylimino)-1,4,14,17-tetraoxa-8,10,21,23-tetraazacyclohexacosanes, were prepared from 1 and a greater excess of diamine 10 (1 : 4) or from 11 and diamine 10.
N-苯基磺酰基二硫代碳亚胺二甲酯(1)与二胺反应后,由于起始原料摩尔比的变化,产生了三种不同类型的产物。从脂肪族二胺中得到了杂环 1 : 1 和无环 2 : 1 反应产物。为了制备大环,1 与 1,10-二氨基-4,7-二氧二十烷(10)发生了反应。通过 1 与 10 的 2 : 1 和 1 : 2 混合反应,分别得到了 1,1′-(4,7-二氧代十亚基)双(2-甲基-3-苯磺酰基异硫脲)(11) 和 9-苯磺酰亚胺-1,4-二氧杂-8,10-二氮杂环十三烷。2 : 2 反应产物 9,22-双(苯磺酰亚胺)-1,4,14,17-四氧杂-8,10,21,23-四氮杂环己烷是由 1 和过量的二胺 10(1 : 4)或 11 和二胺 10 制得的。
