Boron Trifluoride Etherate Mediated Dehydrogenative Nucleophilic Addition Reaction of Aliphatic Ethers in the Presence of Acetal Affording α,β-Unsaturated
Carbonyl Compounds. — The formation of α,β-unsaturated carbonyl compounds
from benzaldehyde dimethyl acetal (I) and aliphatic ethers in the presence of boron trifluoride etherate is reported for the first time. The mechanism of this anomalous conversion is discussed on the basis of experiments with deuterium-labeled precursors.
