Pinacol Coupling of Aromatic Aldehydes using La-Ticl4 in CH3COOEt under Ultrasound Irradiation
Titanium tetrachloride can be reduced by lanthanum filings to the corresponding low valent titanium complex, which can induce some aromatic aldehydes to the corresponding pinacols in 28%-97% yields within 10-50 min in ethyl acetate at r.t. under ultrasound irradiation.
