Tris(cyanoethyl)phosphine is the organophosphorus compound with the formula P(CH2CH2CN)3. It is white solid that is air stable, which is unusual for a trialkylphosphine. It is prepared by the hydrophosphination of acrylonitrile with phosphine.[1] The compound has been the subject of much research. For example, it is an effective reagent for the desulfurization of organic disulfides.[2]
