摘要

实现了 Co(OAc)2/N-hydroxyphthalimide (NHPI) 催化 3-芳基甲基磺酰亚胺氧化制备 3-芳基羰基类似物的新方法。首次从苄基底物全面合成了 3-芳羰基磺酰亚胺。反应以中等到极好的收率进行。机理研究表明，3-(氢过氧基(苯基)甲基)苯并[d]异噻唑 1,1-dioxide A 是生成产物 2 的关键中间体。

Cobalt(II) catalytic oxidation of arylmethyl sulfonyl imines to arylcarbonyl analogues

A novel Co(OAc)₂/N-hydroxyphthalimide (NHPI)-catalyzed oxidation of 3-arylmethyl sulfonyl imines to prepare 3-arylcarbonyl analogues has been realized. 3-Arylcarbonyl sulfonyl imines were comprehensively synthesized from benzyl substrates for the first time. The reactions proceeded in moderate to excellent yields. Mechanistic investigation suggests that 3-(hydroperoxy(phenyl)methyl)benzo[d]isothiazole 1,1-dioxide A is the key intermediate for the formation of products 2.

期刊介绍： Australian Journal of Chemistry - an International Journal for Chemical Science publishes research papers from all fields of chemical science. Papers that are multidisciplinary or address new or emerging areas of chemistry are particularly encouraged. Thus, the scope is dynamic. It includes (but is not limited to) synthesis, structure, new materials, macromolecules and polymers, supramolecular chemistry, analytical and environmental chemistry, natural products, biological and medicinal chemistry, nanotechnology, and surface chemistry. Australian Journal of Chemistry is published with the endorsement of the Commonwealth Scientific and Industrial Research Organisation (CSIRO) and the Australian Academy of Science.
