Die Beständigkeit bekannter photographischer Verschleierungsbäder ist unbefriedigend. Es wurden Verschleierungsmittel enthaltende photographische Bäder gefunden. insbesondere Zinn-II-lonen-haltige Verschleierungsbäder mit einem Zusatz einer Verbindung bzw. eines Tautomeren davon oder eines Salzes dieser Verbindung, welche folgender Formel entspricht, wobei die Substituenten die in der Beschreibung angegebene Bedeutung haben:
摘要:
N-Phenylpyrazole derivatives of the formula:- (wherein each of R 5 and R 6 represents a C 1 -C 4 alkyl or alkoxy radical, a trifluoromethyl, trifluoromethoxy, nitro, cyano or primary amino radical, or a fluorine, chlorine or bromine atom, each of R', R' and R 9 represents a hydrogen atom, a C 1 -C 4 alkyl or alkoxy radical, a trifluoromethyl, trifluoromethoxy, nitro, cyano or primary amino radical or a fluorine, chlorine or bromine atom, or R 5 , R 7 , R' and R 9 each represents a hydrogen atom and R 6 represents a trifluoromethoxy or trifluoromethyl radical, and R 10 represents a cyano radical or substituted carbamoyl radical -CONHR", wherein R" represents a methyl or ethyl radical) have been found to possess useful herbicidal properties. All such N-phenylpyrazole derivatives with the exception of 5-amino-4-cyano-1-(2,4-dichlorophenyl)pyrazole and 5-amino-4-cyano-1- (4-chloro-2-methylphenyl)pyrazole are new compounds. Herbicidal compositions containing such N-phenylpyrazole derivatives are described and also processes for the prepararation of the new compounds.
摘要:
The invention provides novel 1- or 2-adamantylmethyl hydrazines of the general formulaA
In this formula Ad is 1- or 2-adamantyl, R 1 and R 2 are the same or different and are each hydrogen or a lower unsubstituted or substituted alkyl group of 1-4 carbon atoms; R, and R 4 are the same or different and are each hydrogen, an unsubstituted or substituted radical being a lower alkyl group of 1-4 carbon atoms, a lower alkanoic acid radical of 2-4 carbon atoms or a lower alkyl ester thereof, adamantyl, aryl, aralkyl in which the alkyl moiety has 1-4 carbon atoms or an unsubstituted or substituted heterocyclic radical of aromatic character; or R 3 and R 4 together with the nitrogen atom to which they are attached form a cyclic radical of non-aromatic character. The invention further provides pharmaceutically acceptable acid addition salts of the above compounds. Several methods of preparation of the new compounds are described. The novel compounds according to the invention possess valuable antifungal (human and plant), antiviral, antiprotozoal and antimicrobial properties.
