2-dichloroethane at room temperature, S-acylthiol S-oxides 3 are proposed as intermediates. The isolation of carboxylic acid anhydrides and dialkyl disulphides as the actual reaction products can be explained as resulting from the decomposition of the unstable. S-acyl S-acyloxysul-phonium salt 4 arising probably from the reaction of the intermediate S-acylthiol S-oxides with another mole of thiolester.
在室温下在1,2-二氯乙烷中硫酯的臭氧氧化中,提出了S-酰基硫醇S-氧化物3作为中间体。可以将羧酸酐和二烷基二硫化物作为实际反应产物的分离解释为是由于不稳定物质的分解所致。S-酰基S-酰氧基磺基-盐4可能是由中间体S-酰基硫醇S-氧化物与另一摩尔的硫醇酯反应而产生的。然而,在受阻的硫酯的情况下,形成的S-酰基硫醇S-氧化物可能通过S→O酰基转移而重排为相应的酰基亚磺酸盐12,其在进一步氧化时导致混合的羧酸磺酸酐13。
