Carbonyl compounds are successfully converted into oxathioacetals and dithioacetals with 2-mercaptoethanol and ethane-1,2-dithiol using a catalytic amount of iron(iii) fluoride under solvent-free conditions. The catalysts were recovered and reused in various runs without affecting the efficiency of the process.

The elimination of volatile organic solvents in organic synthesis is the most important goal in “Green” chemistry. We report a simple, efficient and facile method for the addition of progargyl bromide to carbonyl compounds using Mg metal as a mediator under solvent-free conditions which could regioselectively generate homopropargyl alcohols efficiently in good to excellent yields. The procedure has advantages such as short reaction time, operationally simple, excellent product yields, high regioselectivity and organic solvent-free.
