formation reaction of simple NH-sulfoximines with 1,4,2-dioxazol-5-ones to produce diverse thiadiazine-1-oxides is reported. The reaction tolerates a broad range of functional groups under external oxidant-free conditions and only releases CO2 and H2O as the sole byproducts. The preliminary mechanistic studies revealed an electrophilic metalation pathway is likely involved in the reaction.
微波辅助的Cp * Co III催化的简单N H-亚磺酰亚胺与1,4,2-二恶唑-5-酮的直接C–H活化/双C–N键形成反应,生成各种噻二嗪-1-氧化物。被报道。在无外部氧化剂的条件下,该反应可耐受各种官能团,并且仅释放出CO 2和H 2 O作为唯一的副产物。初步的机理研究表明,该反应可能涉及亲电性金属化途径。
