The purpose of the invention is to provide a process for advantageous production of dithiocarbonimide derivatives of the formula I: ##STR1##

Process for preparing dithiocarbonimide derivatives

There are disclosed a controlling agent and an antifouling composition against harmful aquatic organisms, which include a particular N-phenylisothiazolone derivative of the formula: ##STR1## wherein X.sup.1 and X.sup.2 are the same or different and are independently hydrogen, chlorine or bromine; and R is haloalkoxy. Also disclosed is a method for preventing or inhibiting the adhesion of harmful aquatic organisms to water-exposed articles, which includes applying the antifouling composition to the water-exposed articles.

Anti-fouling compositions and fouling control of harmful aquatic

The method for producing the benzyl bromide derivatives of the formula: ##STR1## wherein R.sub.1 represents a C.sub.1 to C.sub.5 alkyl group, which comprises reacting a 2-methylphenylacetic acid derivative of the formula: ##STR2## wherein R.sub.1 represents the same meaning above, with bromine in the presence of an alkali metal salt. In case that R.sup.1 is an ethyl or isopropyl group, the recrystallization of the above reaction product from aliphatic hydrocarbon solution gives the benzyl bromide derivatives efficiently and in high purity.

Anti-fouling compositions comprising N-phenylisothiazalone derivatives

There is disclosed a novel isothiazolone derivative of the formula: ##STR1## wherein X.sup.1 and X.sup.2 are the same or different and are independently hydrogen, chlorine or bromine; and R is haloalkoxy. The isothiazolone derivative is effective as a microbicide. Also disclosed are a microbicidal composition containing the isothiazolone derivative as an active ingredient, and an intermediate compound for use in the production of the isothiazolone derivative.
