Process:- R',R" and R''' = H, alkyl (C1-4) or aryl; R" and R"'' together with the ethylene-bridge may form a benzene ring; X = halogen, alkyl (C1-4), alkoxy, nitro, haloalkyl or cyano; n = 0, 1 or 2 (3 in claims) (I) have fungicidal activity against phytopathogenic fungi; Imidazoles (II) are reacted with tritylhalides (IIIe in polar organic solvents with a dielectric constant of at least 4.8, at 9-100 deg.C, in the presence of acid-binding agents. Mol. ratio 1:1 together with 1 mol acid-binding agent. |
