Highly Efficient Microwave-Assisted Substitution of β-Dicarbonyl Compounds with Secondary Alcohols Using Fluoroboric Acid as the Catalyst

The microwave-assisted substitution of β-dicarbonyl compounds with secondary alcohols has been achieved efficiently, using very cheap fluoroboric acid （HBF4） as the catalyst. For various β-dicarbonyl compounds and a series of secondary alcohols, the direct substitution gives high yields after only 5...
