Discovery of neat silica gel as a catalyst: an example of S → O acetyl migration reaction.
Silica gel, widely used in chromatography separation and as a catalyst carrier, was employed here for the first time as a fixed-bed catalyst for the S → O acetyl migration to synthesize thiol compounds under mild conditions, showing the merits of high efficiency, high selectivity, long-life recyclability, low cost and scalable availability.
