2-lithio-4,5-disubstituted-1,3-dithioles react with CS2 in thepresence of an excess organolithium reagents yielding a product of thiophilic addition; subsequent alkylation furnished a new series of2-[bis(alkylthio)methylene]-1,3-dithioles.
在过量的有机锂试剂存在下,2-lithio-4,5-二取代-1,3-二硫醇与CS 2反应,生成亲硫加成产物;随后的烷基化反应提供了一系列新的2- [双(烷硫基亚甲基)亚甲基] -1,3-二硫醇。
