Abstract

3-Phenyl-5-(substituted)-4(1H)-pyridones of the formula I <IMAGE> are prepared by cyclising a compound of the formula IV <IMAGE> in which one of the two substituents Q<1> or Q<2> represents two hydrogen atoms, while the other of the two substituents represents a group of the formula =CHNHR, using a formylating agent. In the compounds of the formulae I and IV, the radicals R, R<1> and R<2>, and m, have the meaning given in Patent Claim 1. The pyridones can be reacted with phosphorus pentasulphide to prepare the corresponding pyridothiones. Both the pyridones and the corresponding pyridothiones, and also the salts of these compounds, are employed as the active component in herbicides. They display their activity against an unusually broad range of weeds.
