- Formation of cyclic sulfonium salts by Me3SiI-promoted intramolecular displacement of hydroxide or methoxide by sulfide. Ring contraction thiepane → thiolane
-
A suitably positioned (1,2-, 1,4-, and 1,5-) intramolecular sulfide interferes with the iodotrimethylsilane-promoted iodine for hydroxyl substitution, as well as the related alcohol deprotection procedure (regioselective cleavage of methyl ethers). The ou

- Et3B Induced Radical Addition of Thiols to Acetylenes
-
Thiols added easily to acetylenic compounds in the presence of Et3B to give alkenyl sulfides in good yields.The reaction of acetylenes with 3-methyl-2-buten-1-thiol gave dihydrothiophene derivatives in one pot.
