Abstract

The invention comprises alkyl-mercury diacylimides of formula <FORM:0770267/IV(b)/1> where R1 is hydrogen or a straight or branchedchain C1-4 aliphatic residue, R2 is a straight or branched chain C1-5 aliphatic residue, R3 is an aromatic carboxylic or heterocyclic ring which may be unsubstituted or substituted with one or more halogen atoms or with one or more C1-3 alkyl radicals, and X is -SO2- or -CO-. R3 may be phenyl, naphthyl, pyridyl or quinolyl. The compounds may be prepared from the diacylimine, which may be prepared by reacting the pentachlorophenoxy fatty acid halide (e.g. chloride) with the aromatic acid amide at a temperature between 150 DEG and 200 DEG C., or by reacting the pentachlorophenoxy acetamide with the appropriate aromatic acid halide (e.g. chloride). The diacylimine so prepared may be reacted with the dialkyl mercury compound, or alternatively the sodium derivative of the diacylimine may be reacted with the alkyl-mercury halide. The compounds may be used as fungicides (see Group VI). In an example: (1) pentachlorophenoxyacetic acid chloride is reacted with p-chlorobenzenesulphonamide to give N-pentachlorophenoxyacetyl - p - chlorobenzenesulphonamide, which in its turn is reacted with diethyl mercury in toluene to give N-ethylmercury-N-pentachlorophenoxyacetyl - p - chlorobenzenesulphonamide. Other examples describe the preparation of N-ethylmercury - N - pentachlorophenoxyacetyl - 3,4,6 - trichlorobenzenesulphonamide, N - isopropylmercury - N - pentachlorophenoxyacetyl - p - chlorobenzenesulphonamide and N - ethylmercury - N - pentachlorophenoxyacetyl - benzamide.ALSO:Fungicidal compositions comprise alkyl mercury diacylimides of formula <FORM:0770267/VI/1> where R1 is hydrogen or a straight or branched chain C2-4 aliphatic residue, R2 is a straight or branched chain C1-5 aliphatic residue, R3 is an aromatic carbocyclic or heterocyclic ring which may be unsubstituted or substituted with one or more halogen atoms or with one or more C1-3 alkyl radicals, and X is -SO2- or -CO. R3 may be phenyl, naphthyl, pyridyl or quinolyl. The compositions may be aqueous suspensions or dusting powders, and may contain kaolin, methylcellulose, sodium sulphate, sulphur and a wetting agent. Specified compounds include N-ethyl-mercury-N-pentachlorophenoxy acetyl-p-chlorobenzene-sulphonamide, -benzamide and -3.4, 6-trichloro-benzenesulphonamide and N-isopropylmercury - N - pentachloro - phenoxy - acetyl - p - chlorobenzenesul - phonamide. In an example (5) a composition comprising kaolin, methyl cellulose, sodium sulphate, a wetting agent and the active compound is described.
