Japanese Patent JPS4943959
Kind Code:
A
Abstract:
In the production of an aryl lactamhydrazone of the formula IN WHICH A represents optionally substituted alkylene, aralkylene or cycloalkylene, each with up to 20 carbon atoms, and Q represents optionally substituted, mononuclear to trinuclear aryl or an optionally alkylsubstituted mononuclear or binuclear heterocyclic aromatic system with 1 to 3 hetero atoms, IN WHICH A LACTIM-ETHER OF THE FORMULA IN WHICH R is aryl or alkyl of 1 to 6 carbon atoms, IS REACTED WITH AN ARYLHYDRAZINE OR HETEROARYLHYDRAZINE OF THE FORMULA H2N-NH-Q (III) the improvement which comprises effecting the reaction at a temperature of about -20 DEG to 150 DEG C and in the presence of at least a catalytic amount of acid, whereby the yield is markedly increased. Those compounds wherein A is -(CH2)2-11- and Q is pyridyl or phenyl substituted by at least one nitro, sulfo, sulfonamido or carboxy group are new and exhibit fungicidal activity.
