Abstract

Abstract An efficient preparation for arylethynyl sulfides 1 and bis (arylethynyl) sulfides 2 has been accomplished through a one-pot, three-step strategy that starts from arylethanonyl sulfides and bis (arylethanonyl) sulfides, respectively, without the use of various terminal arylacetylenes as substrates. When lithium hexamethyldisilazane (LHMDS), ClP (O)(OEt) 2, and LHMDS were sequentially added to a tetrahydrofuran solution of different substrates [ ...
