主　　题：Pinacol synthesis neodymium ultrasound irradiation. 

摘      要：Pinacol coupling reactions of aromatic aldehydes and ketones were carded 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.
