Synthesis of vicinal bis(alkylthio) derivatives by reductive coupling of dithioacetals derived from aromatic aldehydes with low valent titanium iodide species
Reduction of dithioacetals derived from aromatic aldehydes with low valent titanium iodide species in situ formed by treatment of titanium(IV) iodide with zinc in a mixed solvent of dichloromethane and pivalonitrile at room temperature afforded coupling products, vicinal bis(alkylthio) derivatives, in good to high yields.
