摘要
The reduction coupling reactions of aromatic aldehydes were carried out in 31%～92%(or 22%～70%) yield with Zn Powder in water at r.t.for 1 h(or 4 h) under ultrasound irradiation(or stirring).The experimental results show that the proper ultrasound irradiation could speed up the coupling reaction and obtain high yield with simple operation,eco-friendly.
