Synthetic Route of 4265-25-2, The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.4265-25-2, Name is 2-Methylbenzofuran, molecular formula is C9H8O. In a Patent，once mentioned of 4265-25-2
The invention discloses a 2 – substituted benzofuran compound of the catalytic synthesis method, comprises the following steps: normal temperature and pressure, the 2 – alkynyl substituted phenol dissolved in acetonitrile, wherein the 2 – alkynyl substituted phenol with acetonitrile molar volume ratio of 1: 1mmol/mL, to obtain 2 – alkynyl substituted phenol acetonitrile solution; and then to the acetonitrile solution in adding cuprous chloride and cesium carbonate, wherein the cuprous chloride and cesium carbonate of respectively the molar consumption of 2 – alkynyl-substituted phenol mole amount of 5%; after, room temperature stirring 6 hours, produced by the reaction of 2 – substituted benzofuran compound. The invention 2 – substituted benzofuran compound of the catalytic method for synthesis of low cost, high yield, its preparation 1 g of 2 – substituted benzofuran compounds required the cost of the catalyst the prior by iridium catalyst is a catalyst of the synthetic method has lowered 2 orders of magnitude, to improve the yield of the 88.5 – 95.8%.
