Unsymmetrical organic disulfide sulfinate compounds, useful as an antiradiation agents, having the general formula: ##STR1## wherein A is one or of the following polar groups, OH, COOH, SO.sub.3 Na, --C(O)--, or derivatives such as esters and nonamino nitrogen derivatives such as amides or nitriles; k is an integer of one to eight; Y is a straight or substituted aliphatic chain having from two to eight carbon atoms which may have one or more S--S groups interposed therebetween; m signifies the number of carbon atoms in an aliphatic chain Y containing 2 to 8 carbon atoms which may have S--S interposed; aliphatic chain Y, substituted with one or more polar groups of the number k is attached to one of the two sulfur atoms shown. The second sulfur atom is attached through an aliphatic chain of 2 to 5 carbon atoms to the sulfinate function SO.sub.2 M wherein R.sup.1 and R.sup.2 may be hydrogen, aryl, cycloalkyl or various polar groups such as OH, COOH, SO.sub.3 Na, --C(O)--, or derivatives such as esters and nonamino derivatives such as amides or nitriles. The system ##STR2## also may comprise an aromatic ring; n may be the integers 2 through 6; M of the sulfinate function is hydrogen, a metallic element selected from group 1 A of the Periodic Table such as Li, Na, or K, or the equivalent R.sub.4 N+; or an organic group such as a straight or substituted aliphatic chain having up to 4 carbon atoms, designed to promote stability. The synthesis of the compounds occurs by subjecting 1,1-dioxides of cyclic disulfides to the action of a thiolate ion, whereby cleavage is effected between the sulfur and sulfonyl units.
非对称有机二硫醇磺酸盐化合物,可用作抗辐射剂,其通式为:##STR1##其中A是以下一种或多种极性基团之一,OH,COOH,SO.sub.3 Na,--C(O)--,或其衍生物,例如酯和非氨基氮衍生物,例如酰胺或腈;k为1至8的整数;Y为直链或取代的链状脂肪基,其中含有2至8个碳原子,其间可能有一个或多个S-S基团;m表示链状脂肪基Y中含有2至8个碳原子的数量,其间可能有S-S插入;取代了k个极性基团的链状脂肪基Y附着在所示的两个硫原子之一上。第二个硫原子通过一个含有2至5个碳原子的链状脂肪基附着在磺酸盐功能SO.sub.2 M上,其中R.sup.1和R.sup.2可以是氢、芳基、环烷基或各种极性基团,例如OH,COOH,SO.sub.3 Na,--C(O)--或其酯和非氨基衍生物,例如酰胺或腈。该系统##STR2##也可能包括芳香环;n可以是2到6的整数;磺酸盐功能的M是氢、周期表1A族(例如Li、Na或K)中选择的金属元素或等效的R.sub.4 N+;或者是设计用于促进稳定性的直链或取代的含有最多4个碳原子的有机基团。这些化合物的合成是通过将环状二硫醚的1,1-二氧化物置于巯基离子的作用下,从而在硫和磺酰基之间发生断裂。
