-
Paragraph 0095; 0096; 0098-0101, (2018/11/04)
The invention discloses a synthesizing method of an indanone compound. The synthesizing method comprises the following steps of respectively adding a catalyst and an antioxidant into a reaction bottle, then adding a compound shown in a formula (2), adding a solvent, and reacting for 2 to 6h at the temperature of 70 to 120 DEG C under the argon protection atmosphere, so as to obtain the indanone compound, wherein the catalyst is selected from any one of Cu(OAc)2, CuCl2 (copper (II) chloride), CuBr2 (copper (II) bromide), CuO (copper oxide), CuF2 (copper fluoride), Cu(OTf) 2, Cu(OH)2 (copper hydroxide), Cu(NO3)2 (copper nitrate), CuCl (copper chloride), CuBr (copper bromide), CuI (cuprous iodide) and Cu2O (cuprous oxide); the oxidant is tert-butyl hydroperoxide; the solvent is toluene. The synthesizing method has the advantages that a novel concept of the indanone compound is provided; the copper catalyst is used, the price of copper is low, the reserve amount is rich, the environment-friendly effect is realized, and the hydroacylation reaction catalyzed by copper meets the requirements of green chemistry.
