Fungicide and bactericide 3-aryl-3-oxo-propyl-1,2,4-triazole derivs. - prepd. e.g. by reaction of Mannich base with 1,2,4-triazole

摘要

1-(3-Oxopropyl)-1,2,4-triazole derivs. (Ia) and their metal complexes with group Ib, IIb, IVb or VIII metals, as well as their salts and quaternisation prods (Ib) are new. In the formulae R is H, phenyl opt. substd. by halogen and/or 1-4C alkyl, or 1-18C alkyl opt. substd. by halogen, CN or a gp. OR1 in which R1 is 1-4C alkyl, phenyl or phenyl substd. by halogen or 1-4C alkyl; Z is 1- or 2-naphthyl or one of the groups (A), (B) or (C) in which R2 is H, halogen, NO2, CN, OH, 1-6C alkyl, 5-6C cycloalkyl, 1-6C alkoxy, 2-6C alkenyloxy, -(CH2)3-, -(CH2)4- or opt halo-substd. phenyl or phenoxy, R3 is H, 1-4C alkyl or halogen, n is 1, 2, 3 or 4 and m is 1, 2 or 3; R4 is H, 1-18C alkyl, oxoalkyl or alkenyl, or opt. halo-substd. phenacyl; and Y is the anion of an organic or inorganic acid. (I) are fungicides and bactericides esp. useful against rusts and mildews of plants, some cpds. (I) have systemic activity. (I) are also suitable for use in the technical sector, e.g. in timber preservatives, in paints, and as antifungal and antibacterial preservatives.
