A simple, mild and inexpensive catalytic system, DBU and benzyl bromide, was developed for the cycloaddition of epoxides to ambient CO2 under metal-free and solvent-free conditions and a wide range of epoxides was converted to the corresponding cyclic carbonates with good to excellent yields (81–95%).

A highly efficient, green and expeditious solvent-free method is described for the chemoselective conversion of aldehydes to the corresponding acylals in excellent yields, using acetic anhydride in the presence of catalytic amount (20 mol%) of silica-supported LiHSO4. Ketones does not react under these reaction conditions. LiHSO4/SiO2can be recovered and reused without any significant loss of its catalytic activity.
