摘 要: 以苯乙酮类化合物为原料,氧化锌(ZnO)为催化剂,二醋酸碘苯为氧化剂,通过对羰基邻位饱和sp3-C—H键的氧化与乙酰化,成功的构建出了α-乙酸基苯乙酮类衍生物,其结构经1H NMR和13C NMR得到了确认,并提出了可能的反应机理. This paper reports a simple method for the synthesis of a-acetoxyacetophenone derivatives from acetophenones using ZnO as a catalyst and iodobenzene diacetate as an oxidant. This transformation undergoes two processes: the oxidation of saturated sp3-C--H bond and the acetoxylation of C = C bond. The structures of products were confirmed by IR, I H NMR and 13C NMR. In addition, a possible reaction mechanism was proposed.
