Abstract

Process for the anilidization of carboxylic acid esters of the general formula R.sub.1 COOR.sub.2, wherein R.sub.1 is a cycloaliphatic or substituted cycloaliphatic radical with 3-8 C-atoms, preferably 5-6 C-atoms, an aromatic or substituted aromatic radical, preferably a heterocyclic or substituted heterocyclic radical, more particularly an oxygen-containing heterocyclic radical, with 4-5 C-atoms, and R.sub.2 is a hydrocarbon radical with up to 4 C-atoms, preferably 1-2 C-atoms, wherein such esters are reacted in the presence of aniline with equimolar amounts of magnesium dianilide and/or aluminum trianilide in the fluid phase. The products obtained are used as intermediates or directly as pesticides.
