摘要

Abstract When dimethylmethylthiosulfonium triflate (DMTST) is added to a tert-butyl- protected thiol (RSt-Bu), the unsymmetrical disulfide RSSMe is formed. At this point the free thiol (RSH) can be obtained by the addition of trimethylphosphine and water. Most byproducts are small organic molecules that are easily removed.
