1,274,015. Semicarbazide and biuret derivatives. ESSO RESEARCH & ENG. CO. 21 May, 1969 [29 May, 1968; 5 May, 1969], No. 25970/69. Heading C2C. The invention comprises novel semicarbazide derivatives of the formula and novel biuret derivatives of the formula wherein each A 1 -A 10 represents a group-, n 1 -n 10 each represents zero or one; Y represents an oxygen or sulphur atom; R 1 -R 10 and X each represents a C 1 to C 12 alkyl group, a C 1 to C 4 cyanoalkyl group, an alkoxycarbonyl group having from 1 to 4 carbon atoms in the alkyl moiety, an unsubstituted or halo-, C 1 to C 4 alkyl- or C 1 to C 3 alkylthio-substituted phenyl group, a naphthyl group, a cyclohexyl group, a saturated or unsaturated furyl group, an unsubstituted or halo-substituted pyridyl group, or an unsubstituted or halo-substituted anilide group, or taken in pairs, which may be the same or different, attached, via the one or two interposed groups if present, to the same nitrogen atom may, together with that nitrogen atom, represent a saturated or unsaturated, unsubstituted or halo- or alkyl-substituted, unfused or benzo-fused heterocyclic ring system having from 5 to 7 ring atoms more than one of which may be a hetero atom or a group of the formula X or R 5 -R 10 each represents a hydrogen atom; and, where one or more of R 1 -R 10 or X comprises a basic nitrogen atom, a salt thereof. The semicarbazide derivatives of Formula I may be prepared (a) by reacting appropriately substituted carbamoyl or thiocarbamoyl chlorides with hydrazine derivatives or (b) by reacting appropriately substituted hydrazine derivatives with carbon disulphide in the presence of potassium hydroxide, alkylating the products with alkyl halides and reacting the products with substituted amines of the formula or (c) by reacting the above substituted amines with carbon disulphide in the presence of potassium hydroxide, alkylating the products with alkyl halides and reacting the products with hydrazine derivatives. The biuret derivatives of Formula II may be prepared (a) by reacting appropriately substituted carbamoyl or thiocarbamoyl chlorides or mixtures thereof with hydrazine derivatives in a molar ratio of 2 : 1 or (b) by reacting appropriately substituted semicarbazides with carbamoyl or thiocarbamoyl chlorides in the presence of trialkylamines. Fungicidal, bactericidal and herbicidal compositions or plant-growth-regulating compositions contain the above compounds as active ingredients.
