GRAPHICAL ABSTRACT ABSTRACT Dithioacetalization reactions of aldehydes with thiols/thiophenols have been successfully achieved at room temperature by employing the green, bio-basedethyllactate as the reaction medium. By means of this sustainableapproach, a class of dithioacetals has been acquired with high diversity and efficiency.

ABSTRACT Several aldehydes and ketones were efficiently converted into their corresponding dithioacetals and 1,3-dithianes in high yields using catalytic amount of indium(III) chloride in dichloromethane.
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 lowvalenttitanium iodide species in situ formed by treatment of titanium(IV) iodide with zinc in a mixed solvent of dichloro-methane and pivalonitrile at room temperature afforded coupling products, vicinal bis(alkylthio) derivatives, in good to high yields.
