Acetoacetanilide (CH3COCH2CONH2) is the N-phenyl derivative of acetoacetamide. It is also prepared from diketene.[3] It and various derivatives are used in the production of organic pigments called arylide yellows, one example being Pigment Yellow 74. Many analogues have been prepared.[4] To make the dyes, acetoacetanilides are coupled to diazonium salts, "azo coupling".[5]
