| 摘 要： | A simple and effective pinacol coupling of various aromatic aldehydes mediated by gallium in good yields has been carried out. The reaction is highly effective in water in the prurience of KOH or HCl and was strongly affected by the steric environ-ment surrounding the carbonyl group. Aliphaflc aldehydes, ke-tones and aromatic ketones appear inert under the same reac-tion conditions.

| Abstract: | A simple and effective pinacol coupling of various aromatic aldehydes mediated by gallium in good yields has been carried out. The reaction is highly effective in water in the presence of KOH or HCl and was strongly affected by the steric environment surrounding the carbonyl group. Aliphatic aldehydes, ketones and aromatic ketones appear inert under the same reaction conditions. |
