Bromination of 2,5-disubstituted 6a-thiathiophthens [1,6,6aS(IV)-trithiapentalenes] yields monosubstitution products, but nitrosation is accompanied by rearrangement, leading to 3-nitrosomethylene-1,2-dithioles in which the oxygen atom of the nitroso-group is probably bonded to the adjacent sulphur atom. 2-Methylthio-5-phenyl-6a-thiathiophthen undergoes nitration in the 3-position.
2,5-二取代的6a-硫代噻吩[1,6,6aS(IV)-三硫杂戊酮]的溴化生成单取代产物,但亚硝化反应伴随重排,导致3-亚硝基亚甲基-1,2-二硫醇的氧原子亚硝基可能与相邻的硫原子键合。2-甲硫基-5-苯基-6a-硫代噻吩在3-位进行硝化。
