Patent number: 4837308Abstract: A universally usable process for preparing azo dyestuffs by oxidative coupling consists in carrying out the oxidation in the presence of redox mediators with a standard potential of 0.2-1.5 volts and, if appropriate, an additional oxidizing agent with a standard potential of 0.25-2.5 volts, wherein the sum of the oxidation equivalents should be at least 4. The preferred redox mediator is iodine. The process is particularly suitable for the preparation of heteroaromatic azo dyestuffs using an aniline coupling component.Type: GrantFiled: January 12, 1988Date of Patent: June 6, 1989Assignee: Bayer AktiengesellschaftInventor: Rainer Gerlach
