3H)-dithione (1) with p-xylylene diisothio-cyanate, reacted with N,N′-dialkyl substituted diamines to give macrocyclic compounds bearing hypervalent sulfur by a ring closure reaction in good yields. These macrocyclic compounds were converted into ring-expanded macrocyclic compounds with release of the hypervalent sulfur by treating with NaBH4 and CF3COOH.
2,3-双[(对-异硫氰酸根合甲基苯基)甲基] -6,7-二氢-5 H -2a-thia(2a-S IV)-2,3,4a,7a-四氮杂-环戊[ cd ] indene-1由2,3-二甲基-6,7-二氢-5 H -2a-thia(2a-S IV)-2,3,4a反应制得的,4(2 H,3 H)-二硫酮(3),7a-四氮杂环戊基-[ cd ]茚-1,4(2 H,3 H)-二硫酮(1)与p-二甲苯二异硫氰酸酯与N,N'-二烷基取代的二胺反应,以良好的收率通过闭环反应得到带有高价硫的大环化合物。通过用NaBH 4和CF 3 COOH处理,这些大环化合物在释放出高价硫的情况下转化为扩环的大环化合物。
