Under ultrasound irradiation, the pinacol coupling of aromatic aldehydes with Mn-NHjCl or Mn-MnC2 in aqueous THF was achieved in 30% - 95% yields at room temperature for 2-3 h. Compared with classical methods, the main advantages of the present procedure are short reaction time, less reductive agent and high yield
