摘要： A method for producing compounds of general formula (I): wherein R1 and R2, each time they occur and independently of each other, mean hydroxyl, C1-6-alkyl, C1-6-alkoxy, halogen, phenyl or phenoxy; R3 means hydrogen or C1-6-alkyl; m is a whole number from 0 to 4; and n is a whole number from 0 to 5. According to the method, diketene is reacted with an N-phenyl-p-phenylenediamine of general formula (II): wherein R1, R2, R3, m and n have the meanings given above, in the presence of 3 to 40 percent acetic acid and at temperatures of 20 to 100° C. The compounds (I) with R3 is C1-6-alkyl and the enamines can be obtained from these by reaction with ammonia, and their hydration products.
