Ds. Bose et al., Efficient method for selective cleavage of acetals and ketals using peroxymonosulfate on alumina under solvent-free conditions, SYNTHESIS-S, (1), 2000, pp. 67-68
In an environmentally benign solvent-free system, acetals and ketals are ra
pidly cleaved with peroxymonosulfate-alumina under microwave irradiation in
high yields.
