title: Pinacol coupling of aromatic aldehydes and ketones using TiCl3-Mg under ultrasound irradiation.
abstract: Titanium trichloride in EtOH can be reduced by Mg to the corresponding low valent titanium complexes, which can reduce some aromatic aldehydes and ketones to the corresponding pinacols in 8-95% yields within 15-40 min under ultrasound irradiation.
