Patent number: 4704469Abstract: A method for the preparation of 2-halogenoresorcinols having the following formula I ##STR1## where X represents a halogen atom and R and R.sub.1 may be the same or different and represent a hydrogen atom or a free organic functional or functionally modified group or a hydrocarbon group, which may be substituted by one or more free organic functional or functionally modified groups and R and R.sub.1 jointly may also represent a free organic functional or functionally modified group or a hydrocarbon group which may be substituted by one or more free organic functional or functionally modified groups, and esters, ethers, or salts thereof.The method comprises sulfonating the corresponding resorcinols which do not contain a halogen in the 2-position and then halogenating the sulfonic acids thus obtained. The halogenated sulfonic acids thereby obtained are subsequently protodesulfonated by acid hydrolysis and, if desired, any functional groups which may be present can be modified.Type: GrantFiled: December 21, 1984Date of Patent: November 3, 1987Assignee: Fidia S.p.A.Inventors: Francesco D. Valle, Aurelio Romeo
