1,3-Diketones were synthesized from alpha,beta-unsaturated ketones by treatment with acid chlorides and Et(2)Zn in the presence of RhCl(PPh(3))3. This is a very simple and extremely chemoselective reaction to give the adduct at the alpha-position of alpha,beta-unsaturated ketones.
1,3-二酮是由α,β-不饱和酮通过在RhCl(PPh(3))3存在下用酰氯和Et(2)Zn处理而合成的。这是一个非常简单且极具化学选择性的反应,可在α,β-不饱和酮的α-位上产生加合物。
