This invention relates to novel hydroxyimino-substituted naminoacetonitriles, which are intermediates in the preparantion of substituted 2-aminopyrazines, which latter comnpounds are intermediates in the preparation of insecticidal nbenzoylpyrazinylureas. The hydroxyimino-substituted aminnoacetonitriles are of the formula n nwherein nR¹ is hydrogen or C₁-C₄ alkyl; nR² is hydrogen, halo, C₁-C₃ alkyl, or trifluoromethyl; nn is 0,1 or 2, with the proviso that when n=2, only one northo position may be substituted; and nR³ is C₁-C₄ alkyl. n These compounds are prepared by reacting an aminnoacetonitrile with the appropriate α-chloro or α-bromo noxime. |
