A highly regio- and enantioselective allylic alkylation of sodium thiophenoxide has been realized by [Ir(COD)Cl]2/phosphoramidite along with CsF as an additive, producing highly enantioenriched allyl phenyl sulfide compounds with up to 99% ee.

Thioalkoxyphosphonium salts, Ph3PSR(1+)*ClO4(1-) (3) and Bu3PSR(1+)*X(1-) (X=ClO4 and BF4) (5), have been prepared from the corresponding tertiary phosphines and disulfides by simple procedures, which involve (i) constant current electrolysis in acetonitrile in the presence of either HClO4 (for 3) or PhCOOH and LiX (for 5), and (ii) stirring an equimolar mixture of a phosphine, a disulfide, PHCOOH, and LiX in acetonitrile at ambient temperature.For the preparation of 3, which have been reported as useful reagents for the synthesis of unsymmetrical disulfides, the electrochemical method is recomended, while for 5 the latter non-electrochemicl procedure gave better results.Reactions of the phosphonium salts 5 with carboxylic acidsand primary alcohols in benzene at ambient temperature gave thiolesters and unsymmetrical sulfides, respectively, in fair to excellent yields.Keywords - triphenylphosphine; tributylphosphine; disulfide; thioalkoxyphosphonium salt; thiolester; unsymmetrical sulfide
