1530172 Substituted imidazoles ROHM & HAAS CO 2 Feb 1976 [5 Feb 1975 12 March 1975 18 Dec 1975 7 Jan 1976] 04011/76 Heading C2C [Also in Division A5] The invention comprises a substituted imidazole or metal salt complex or an agronomically acceptable acid addition salt thereof, said substituted imidazole being of the formula: wherein: Z (when not joined to R2) is a group containing up to 18 carbon atoms and is aryl; substituted aryl; aryl so substituted as to form a fused carbocyclic or heterocyclic ring; saturated carbocyclic so substituted as to form a fused aryl ring; or a heterocyclic group; R1(when not joined to R2) is hydrogen (except when R2 is hydrogen), cyano, (C 1 -C 20 )alkyl, (C 3 -C 8 )cycloalkyl, (C 2 -C 12 )alkenyl, (C 5 -C 8 )- cycloalkenyl, (C 3 -C 6 )alkynyl or aralkyl of up to 24 carbon atoms which aralkyl group is optionally substituted with up to 3 substituents which may be the same or different; R2 (when not joined to Z or R1) is hydrogen or a group containing up to 20 carbon atoms and which is (C 1 -C 20 )alkyl, (C 2 -C 12 )alkenyl, (C 3 - C 6 )alkynyl, (C 3 -C 8 )cycloalkyl, (C 5 -C 8 )cycloalkenyl, aryl or aralkyl, the last two groups being optionally substituted; R1 and R2 (when joined together) form, together with attached carbon atom, a (C 3 -C 8 )- cycloalkyl residue; Z and R2 (when joined together) form the group A is a (C 1 -C 5 )alkylene group X is halogen, nitro or (C 1 -C 4 )alkyl, the X substituents being the same or different when more than one is present; a is zero, 1 or 2, and n is zero or 1. Methods of preparation of these compounds and their precursors are given. The compounds may be used as fungicides.
