Abstract
Novel chloropyridylcarbonyl derivatives of the formula ##STR1## in which Het is ##STR2## n is 1 or 2, R.sup.1 is hydrogen, optionally substituted C.sub.1-6 alkyl, optionally substituted C.sub.2-6 alkenyl, optionally substituted C.sub.3-6 alkynyl, optionally substituted phenyl or optionally substituted pyrimidinyl, and R.sup.2 and R.sup.3, independently of each other, are hydrogen or C.sub.1-4 alkyl, and acid addition salts and metal salt complexes thereof, are outstandingly active as microbicides.
Claims5
A chloropyridylcarbonyl derivative of the formula ##STR40## in which Het is ##STR41## n is 1 and the chlorine atom is bonded to the 2-position of the pyridyl group or
- n is 2 and the chlorine atoms are bonded to the 2- and 6-position of the pyridyl group,
- R.sup.1 is hydrogen or is C.sub.1-4 alkyl, optionally substituted by one to three identical or different substituents selected from halogen, phenyl, cyano, C.sub.1-4 alkoxy, C.sub.1-4 alkoxycarbonyl, or
- R.sup.1 is C.sub.2-4 alkenyl, optionally substituted by one to three identical or different substituents selected from C.sub.1-4 alkoxy or
- R.sup.1 is phenyl.
