A Mitsunobu approach for the synthesis of sulfinate esters by direct nucleophilic substitution of alcohols is described. The salient features of this strategy include neutral and metal-free conditions for the rapid synthesis of sulfinates in high yields. The present protocol using p-toluenesulfonylmethyl isocyanide (TosMIC) and the triphenylphosphine (TPP)/diisopropyl azodicarboxylate (DIAD) reagent system represents the general synthetic route to this important class of compounds.

Two simple and efficient methods for the synthesis of sulfinate esters and thiosulfonates from sodium salts of sulfinic acids are described. Different alcohols were converted into the corresponding sulfinate esters in good yields and purity in an open flask. By the adjustment of the reaction conditions thiosulfonates could also be obtained in a very short reaction time.
Water-soluble polymer-bound, recoverable palladium(0)-phosphine catalysts
Bergbreiter, David E.,Liu, Yun-Shan
, p. 7843 - 7846 (2007/10/03)
The synthesis of a water-soluble polymer-bound Pd(0)-phosphine catalyst is described. This soluble polymeric catalyst is soluble in aqueous or mixed aqueous/organic media and has high activity in nucleophilic allylic substitution and in sp-sp2 coupling reactions of aryl iodides with terminal alkynes. The catalyst can be recycled efficiently by solvent or thermal precipitation methods.
