Abstract

A process for the industrial production of 4,4'-bis- (acylaminomethylene) -1,1'-dipyridylidenes of the general formula ** (see formula) ** Wherein r is a saturated or unsaturated alkyl group, a homocyclic or heterocyclic aromatic ring with or without substituents or a saturated or unsaturated cycloalkyl, characterized by reacting an N- (4-picolyl) -amide or preferably its k-oxide of formula ** (see formula) ** Wherein r has the meaning indicated above, with halides or acid anhydrides at temperatures above 11º c, with or without solvents, between one and twenty-four hours, precipitating the product in the reaction, and then filtering and purifying by crystallization in an appropriate solvent in the usual manner.
