Chloropyridylcarbonyl derivatives and their use as microbiocides

摘要

Novel chloropyridylcarbonyl derivatives of the formula <CHEM> in which Het is <CHEM> n is 1 or 2, R<1> is hydrogen, optionally substituted C1-6 alkyl, optionally substituted C2-6 alkenyl, optionally substituted C3-6 alkynyl, optionally substituted phenyl or optionally substituted pyrimidinyl, and R<2> and R<3>, independently of each other, are hydrogen or C1-4 alkyl, and acid addition salts and metal salt complexes thereof, processes for the preparation of the new compounds and their use as microbicides.
