Abstract
The reaction of dimethyl sulfide ditriflate with dimethyl sulfide lead s to the formation of tetramethyldisulfonium ditriflate 1a representin g a first example of acyclic S-S dication. Similarly was prepared S-S dication 1b from tetrahydrothiophene. It was found that dications 1a a nd 1b react with arylalkenes. The reaction forms the corresponding 1,2 -disulfonium salts. Conjugated dienes afford 1,4-disulfonium salts. (C ) 1998 Elsevier Science Ltd. All rights reserved.
