2-Imidazoline-5-ones derivatives as fungicides.

摘要

2-imidazoline-5-one derivs. of formula (I), their salts, stereoisomers and enantiomers, partic. the 2 enantiomers of the cpds. with an asymmetric carbon atom in the imidazoline ring carrying R1, are new. R1 = H, vinyl or allyl or 1-3C alkyl or haloalkyl; n = 0 or 1; Y = O or S; R2 = H, haloalkyl or cyclopropyl; R3 = aryl or heteroaryl, phenyl, naphthyl, pyridyl; R4 = H, formyl or aroyl, 2-6C acyl, 2-6C alkoxycarbonyl, aryloxycarbonyl; W = O, S or SO; Ar1 = divalent radical arising from an aryl or heteroaryl gp; Ar2 = 5-10 atom mono- or bi-cyclic gp., aromatic, opt. unsatd., opt. contg. 1-4 heteroatoms (O, S or N); X = -(R'')j-A-(R')k-; j, k = 0 or 1; R'', R' = 1-6C hydrocarbon chain, opt. unsatd.; A = O, S, SO, SO2, CO, CS.
