Reaction Profile

Various 1,3-dicarbonyl compounds reacted readily with benzylic alcohols in the presence of Cs2.5H0.5PW12O40 salt to produce 2-benzylic-1,3-dicarbonyl compounds in high yields. It was found that this catalyst could be completely recovered and reused without loss of its catalytic activities and is thus environmentally conscious especially in solvent-free conditions. The use of this method provides improved modification of the direct benzylation of 1,3-carbonyl compounds in terms of low reaction times, solvent-free conditions, usage of a small amount of the catalyst, and a clean reaction profile. Furthermore, the use of this catalyst is feasible because of its easy preparation, its easy handling, its stability, its easy recovery, its reusability, being environmentally green, its excellent activity, and its selectivity.

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.
