The feasibility of insertions of carbanions between two sulfur atoms has been reported when 5-(4-chlorophenyl)-4-cyano-1,2-dithiol-3-thione (1) and tetramethylthiuram disulfide (17) were allowed to react with unsaturated 2a,b and active phosphonium salts 11a,b. The reactions afforded, mainly, 1,3-dithiols 4a,b and 14a,b together with substituted thiophenes 10a,b and 16a,b. Reactions of 1 and 17 with
当使5-(4-氯苯基)-4-氰基-1,2-二硫醇-3-硫酮(1)和四甲基秋兰姆二硫化物(17)与不饱和化合物反应时,已经报道了在两个硫原子之间插入碳负离子的可行性。2a,b和活性phospho盐11a,b。反应主要得到1,3-二硫醇4a,b和14a,b以及取代的噻吩10a,b和16a,b。的反应1和17用α-烷基硫代膦酸酯24A,B,得到膦酸酯25a和25b和图26A,B分别。
