A method of preparing a 2-acylresorcinol which comprises dehydrogenating a 2-acyl-1,3-cyclohexanedione of the general formula
wherein R¹ represents an alkyl, aralkyl or aryl group, and RZ represents hydrogen, or an alkyl, alkoxy or acylamino group, in the presence of a dehydrogenation catalyst (such as a Group VIII metal) or a dehydrogenation agent (such as sulphur or selenium) at an elevated temperature, to provide a 2-acylresorcinol of the general formula
wherein R¹ and R² are as defined.
一种制备2-酰基邻苯二酚的方法,包括在存在脱氢催化剂(如第VIII族金属)或脱氢剂(如硫或硒)的情况下,将一般式中R¹代表烷基、芳基或芳基的2-酰基-1,3-环己二酮进行脱氢反应,反应温度升高,得到一般式中R¹和R²如定义的2-酰基邻苯二酚。
