Silyl-benzimidazole-2-carbamic acid esters of the formula I ##STR1## where Y and Z are hydrogen or a silyl radical of the formula ##STR2## where R.sup.1, R.sup.2 and R.sup.3 independently of one another are unsubstituted or halogen-substituted alkyl, alkenyl or alkynyl of up to 12 carbon atoms, cycloalkyl of up to 7 carbon atoms which is unsubstituted or substituted by alkyl or alkynyl of up to 4 carbon atoms, or phenyl which is unsubstituted or substituted by halogen or alkyl of up to 4 carbon atoms, and R is alkyl of up to 4 carbon atoms, with the proviso that Y and Z are not both hydrogen, and their use as fungicides.The new active ingredients are particularly suitable for combating harmful phycomycetes, ascomycetes and fungi imperfecti.
摘要:
Sulfonamides are prepared by reacting ammonia or an amine with a halosilane and then reacting the resulting silylamine with sulfuryl chloride in the presence of a solvent which is inert under the reaction conditions.The sulfonamides are used as intermediates for drugs and crop protection agents, and are starting materials for the preparation of alkylamidosulfonyl chlorides.
摘要:
Butadiene dinitriles are prepared by reacting a quaternary ammonium compound with malodinitrile in the presence of an alkanol and then reacting the product with an alkali metal compound.The butadiene dinitriles obtainable by the process of the invention are valuable starting materials for the preparation of dyes, pesticides, drugs and vitamins.
