Abstract: The invention relates to a method of producing compounds comprising two nitrile functions. More specifically, the invention relates to a method of producing dinitrile compounds from compounds comprising a nitrile function and an ethylenic unsaturation, in the presence of a catalytic system containing an organometallic complex and a Lewis acid-type cocatalyst. The inventive method comprises a step involving treatment of the reaction medium resulting from hydrocyanation, enabling the metallic element to be extracted and recovered from the Lewis acid.
