Aminoxylation of Thioalkynes through Radical-Polar Crossover

, p. 592 - 594 (2020)
A one-pot procedure for the aminoxylation of thioalkynes for the direct formation of α-functionalized thioesters under mild reaction conditions is reported. A ketenethionium ion is the key intermediate, which is generated in situ by Bronsted acid mediated protonation and undergoes a radical-polar crossover.

A formal [2 + 2] cycloaddition of 4-phenyl-1,2,4-triazoline-3,5-dione (PTAD) with electron-rich alkynyl sulfides and selenides is described. These investigations provide a convenient method to access diazacyclobutenes in good yield while tolerating a rela

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 [arylethanonyl sulfides or bis(arylethanonyl) sulfides], 1 or 2 were obtained in moderate to good yields. The reaction procedure involves the formation of an enol phosphate and a subsequent base-induced elimination. An efficient preparation of arylethynyl sulfides 1 and bis(arylethynyl) sulfides 2 has been accomplished by a one-pot, three-step strategy that starts from arylethanonyl sulfides and bis(arylethanonyl) sulfides, respectively, to give 1 and 2 in moderate to good yields. The reaction mechanism involves the formation of an enol phosphate that undergoes a subsequent base-induced elimination. Copyright

Pyrolysis of α-acyl,α-thio phosphoranes affords thioacetylenes in a good yield.The thio acethylenes are precursors of terminal and alkyl disubstituted acetylenes.
