ABSTRACT:
Process for the production of 4-(trialkylammonium)-acetoacetarylides having the formula: ##STR1## wherein: R is H, a lower alkyl, --OCH.sub.3, --OC.sub.2 H.sub.5, --Cl, --Br, --NO.sub.2, --NHCOCH.sub.3 or an anilated heterocyclic ring; n is 1 to 3; R.sup.1, R.sup.2 and R.sup.3 each is an alkyl having 1 to 18 C atoms; and X is Cl or Br. Such arylide is prepared by reacting a corresponding trialkylamine with a corresponding 4-haloacetoacetarylide at a low temperature in the presence of an organic solvent.
