Recyclable heterogeneous gold(I)-catalyzed oxidation of internal acylalkynes: Practical access to vicinal tricarbonyls

A highly efficient heterogeneous gold(I)-catalyzed oxidation of internal acylalkynes has been developed using 2,6-dichloropyridine N-oxide as the oxidant in dichloromethane (CH2Cl2) at room temperature, providing a novel and practical approach for the construction of diverse vicinal tricarbonyls such as α,β-diketoesters, 1,2,3-triketones, and α,β-diketoamides in good to excellent yields. The heterogeneous gold(I) catalyst can be readily obtained via a simple preparative procedure from commercially available reagents and recovered by filtration of the reaction mixture and reused up to seven times without significant loss of catalytic efficiency.

Singel-Oxygen Photolysis of Dihaloketones. A Facile and Efficient Approach to Vicinal Triketones and Their Monohydrates

The preparation of vic-triketones and/or their monohydrates by sensitized photooxidation (singlet oxygen) of gem-dihaloketones and/or vic-dihaloketones is described; some reaction mechanisms are discussed.
