Abstract
HBF4-SiO2 has been found to be an outstanding catalyst for the protection of carbonyl compounds as acylals under entirely solvent-free conditions. Some of the major advantages of this procedure are high yields, ease of operation, high chemoselectivity, high atom efficiency, and compatibility with other protecting groups.
Key words
acylals - carbonyl compounds - chemoselective - HBF4-SiO2 - protection
