Title:
MANUFACTURE OF HALOGEN COMPOUNDS OF THYMOLS
Document Type and Number:
Japanese Patent JPS59143081
Kind Code:
A
Abstract:
PURPOSE:To obtain easily halogenothymols under mild conditions using a halogen-contg. salt easy to handle by ahlogenating thymols represented by a specified general formula by electrolytic halogenation in place of a reaction with a halogenating agent. CONSTITUTION:Thymols represented by formula I (where R is H or aminoalkyl) are electrolytically halogenated in an org. solvent contg. an inorg. salt such as LiClO4 or NaClO4 or an org. salt such as tetraethylammonium perchlorate as an electrolyte. Halogenothymols represented by formula II (where each of substituents X is H or halogen, yet both of them are not H) can be obtd. under mild conditions in a high yield.
