The addition of thiols to methylpropiolate was remarkably accelerated in the presence of alumina to give the Z-isomer of the 1:1 adducts stereoselectively, in which alumina acts as a bifunctional catalyst of acid and base.

An increasing number of reactions of sulfenic acidanions are being demonstrated in the literature. As such, mild, general and reliable means for the generation of sulfenates are due. In the current paper, an addition/elimination of 2-sulfinyl acrylates using various nucleophiles is demonstrated and evaluated as a protocol for alkane- and arenesulfenate generation. Cyclohexanethiolate, methoxide and
