which formed salts with electrophiles (7, 8) as well as with bases. The crystal structure of 5a was determined. Oxidation of the dithioles 5a and 6a led to S(2)-oxides (10a, 11a) and the corresponding S(2)-dioxides (10b, 11b) depending on reaction conditions. The thiosulfinate 10a was converted by a ring-opening/ring-closure reaction sequence to the bicyclic sulfinamide 12. The oxidative addition reactions
从吡咯烷酮4制备标题化合物。亲核置换和闭环反应产生了二硫杂吡咯5a,其与亲电试剂(7、8)以及与碱形成盐。确定了5a的晶体结构。根据反应条件,二硫醇5a和6a的氧化导致S(2)-氧化物(10a,11a)和相应的S(2)-二氧化物(10b,11b)。通过开环/闭环反应序列将硫代亚磺酸盐10a转化为双环亚硫酰胺12。[Pt(η2 -C 2 H 4)(PPh 3)2 ](14)与二硫化物5a和13的氧化加成反应分别导致二硫代铂(II)络合物15和16。配合物16在结构上被表征。通过14与硫代亚磺酸盐10a的反应合成了磺基-硫醇基络合物17。硫代磺酸钠Pt II配合物18是通过Pt的氧化插入而制备的0进入相应的硫代磺酸盐10b的CS键中。此外,复合物18的特征在于单晶X射线衍射研究。
