摘要 |
Disclosed is an improved method for the preparation of highly pure haloformimine compounds in high yields by reacting a formimine compound in a solvent with a halogenating agent while maintaining the pH of the halogenation reaction in the range of 2 to 5. The pH of the reaction may be maintained by a variety of means, such as by the addition of a base.
