Copper-Catalyzed N-N Bond Formation by Homocoupling of Ketoximes via N-O Bond Cleavage: Facile, Mild, and Efficient Synthesis of Azines
摘要:
A facile, mild, and efficient copper-catalyzed homocoupling of ketoximes involving N-O bond cleavage in the presence of sodium bisulfite (NaHSO3) has been developed. This reaction shows good functional group tolerance and affords a broad scope of azines in high yields.
