The invention relates to novel heterocyclic compounds, their acid addition salts and metal complexes, as well as their stereoisomers, and their preparation. The compounds of the invention correspond to the formula: (CF DRAWING IN BOPI) in which R is an optionally substituted phenyl radical; R ** 1, R ** 2, R ** 3 represent H, a halogen or an alkyl or trialkylsilyl radical; R ** 4 represents H or an alkyl group, with the proviso that R ** 1 to R ** 4 do not all represent H and that when R ** 1 and R ** 2 represent H, R ** 3 is not an alkyl group; and R ** 5 is hydrogen or an organic group. Application: fungicides and substances influencing plant growth. |
