摘要

A process for the preparation of halides of N-halo-N-phenyl-N', N'dimethylformadinium, active component of fungal controlling agents, of structural formula **(See formula)** where R is selected from the group consisting of hydrogen, C1-C6 alkoxy, C1-C6 alkylthio, C1-C6 alkyl, bromine and chlorine, n is an integer ranging from 1 to 4; X is selected from the group consisting of bromine and chlorine, characterized in that an N, N-dimethyl-N'-phenylformamidine is reacted with a halogen, such as chlorine or bromine, according to the chemical equation **(See formula)** in I/II molar ratios between 1: 1 and 2: 1 and preferably 1: 1, in an inert solvent medium, in the absence of light, the reaction being conducted at temperatures between -30 and -25ºC and preferably between -10º and + 10ºC, under atmospheric pressure.
