摘要：
A cobalt-catalyzed redox-neutral [4 + 2] annulation of oximes and alkynes in deep eutectic solvents comprising quaternary ammonium compounds and hydrogen bond donors has been developed, the best system being Me3N+CH2CO2-/HOCH(CF3)2. No external oxidizing reagent was required, and only water was generated as the secondary product. The catalytic system can be reused in three consecutive cycles.
