The reaction of a wide range of alkynes with thiols to give vicinal dithioethers in water, under mild conditions, is reported. In addition, non-terminal propargyl alcohols react with aryl thiols in water to produce a highly regio- and stereoselective monohydrothiolation product, (E)-alkenyl thioether. Reaction mechanism and computational studies on the selectivity of the product are presented.
The boron trifluoride-promoted reaction of a series of 3'- and 4'-substitutedbenzenesulphenanilides (1) with various alkenes has been investigated as a potential synthetic route to arylaminosulphides. The benzenesulphenanilides (1) investigated generally afford arylamino-sulphenylation adducts in fair to good yields except for the methoxy-substituted anilides (le and f), which largely lead to decomposition
