Sulfonyl esters 7. The second and third sequences in the Trithioorthoformate Reaction

A previous report has established the intermediacy of a sulfide-sulfonate ester in the one-pot conversion of an aryl mercaptan and a sulfonate ester into the corresponding trithioorthoformate. This report describes evidence for the sequential intermediacy of a bissulfide-sulfonate ester and a dithiosulfene in the conversion of the sulfide-sulfonate ester into the trithioorthoformate. A new sulfonate ester is shown to give the highest yield of trithioorthoformate.

Sulfonyl esters. 3. The formation of sulfone-sulfonates in the reactions of aryl methanesulfonates with sodium borohydride

Sodium hydride reductions of aryl methanesulfonates afford dimeric sulfone-sulfonate esters as well as products arising from SO bond rupture.SO bond rupture becomes more competitive as the LUMO energy of the sulfonate ester declines.Exploration of the chemistry of a sulfone-sulfonate ester revealed a complex novel reaction that resulted in the formation of, inter alia, a dichloromethanesulfonate ester and a trichloromethanesulfonate aster.The first succesful approaches to the synthesis of the heretofore unknown trichloromethanesulfonates and dichloromethanesulfonates are reported.Key words: sodium hydride reductions, sulfenes, sulfone-sulfonate esters.
