| abstract |
A method of preparing a 2-acylresorcinol which comprises dehydrogenating a 2-acyl-1,3-cyclohexanedione of the general formulan wherein R¹ represents an alkyl, aralkyl or aryl group, and R Z 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 formulan wherein R¹ and R² are as defined. |
