Al(HSO4)3 as an efficient catalyst for acetalization of carbonyl compounds under heterogeneous or solvent -free conditions. J. Braz. Chem. Soc. [online]. 2005, vol.16, n.4, pp.877-880.

Al(HSO4)3 as a solid acid was applied for acetalization of carbonyl compounds at room temperature and under solvent-free conditions with good to excellent yields. The cheapness and availability of this reagent with easy procedure and work-up make this method attractive for the organic synthesis.
