Novel triethylamine catalyzed S → O acetyl migration reaction to generate candidate thiols for construction of topological and functional sulfur-containing polymers

Various sulphur-containing monomers and polymer materials transformed from different epoxy compounds.

Discovery of neat silica gel as a catalyst: an example of S → O acetyl migration reaction

For the first time, we reported pristine silica gel as an efficient fixed-bed catalyst for S → O acetyl migration to obtain important thiol compounds under mild reaction conditions.
