Fund Project: The project was supported by the Natural Science Foundation of Hebei Province (203107) and the Science Foundation of Hebei Langfang Normal College (200517).

Pinacol coupling reactions of aromatic aldehydes and ketones were carried out using Nd-36% HOAc-CH₂Cl₂ system with stirring at r. t. for 4 h (in 14-70% yield). The reactions in the same system gave pinacols in 10-93% yield under ultrasound irradiation at r.t.for 2 h.
