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-酰基间苯二酚的方法,包括将通式如下的 2-酰基-1,3-环己 二酮脱氢
其中 R¹ 代表烷基、芳基或芳基,RZ 代表氢或烷基、烷氧基或酰氨基,在脱氢催化剂(如第 VIII 族金属)或脱氢剂(如硫或硒)存在下,在高温下脱氢,得到通式的 2-酰基间苯二酚。
其中 R¹ 和 R² 如所定义。
