In this study, first direct access to aryl alkyl sulfides employing 2?
phenylpropanal as coupling partner is reported. Diaryl disulfides react with
this aldehyde in the presence of morpholine and produce the corresponding
sulfide products in high yields. In another part, disulfides are in situ generated
in the reaction mixture from aryl halides/CuI/Cyanodithioformate and coupled
with 2?phenylpropanal to access aryl alkyl sulfides.
