The regioselective reaction of 2-bromomethyl-1,3-thiaselenole 1 with thiourea is accompanied by rearrangement, expanding the ring to afford the corresponding six-membered isothiuronium salt, 2-[amino(imino)methyl]sulfanyl-2,3-dihydro-1,4-thiaselenine hydrobromide 2, a synthon of the 2,3-dihydro-1,4-thiaselenin-2-ylthiolate anion. The latter was used for the synthesis of the first representatives of
2-溴甲基-1,3-硫杂亚硒酸酯1与硫脲的区域选择性反应伴随重排,扩大环以提供相应的六元异硫脲鎓盐2- [氨基(亚氨基)甲基]硫烷基-2,3-二氢-1,4-硫代丝氨酸氢溴酸盐2,是2,3-二氢-1,4-硫代丝氨酸-2-基硫醇盐阴离子的合成子。后者用于合成2-(有机基硫烷基)-2,3-二氢-1,4-硫代丝氨酸3a - g的首个代表,双(2,3-二氢-1,4-硫代丝氨酸-2-基)二硫化物5和1,6-双(2,3-二氢-1,4-硫代木素-2-基硫基)己烷6。
