Mercury-Catalyzed Rearrangement of Ketoximes into Amides and Lactams in Acetonitrile
摘要:
An acetonitrile solution of mercury(II) chloride has been found to catalyze efficiently the conversion of a diverse range of ketoximes into their corresponding amides/lactams.
[figure: see text] Beckmann rearrangement of oxime is catalyzed by [RhCl(cod)]2, trifluoromethanesulfonic acid, and tris(p-tolyl)phosphine in refluxing dichloroethane, giving the corresponding amide in good yield. Product/acid ratios of 10:20 can be attained in the reaction of benzophenone oximes.

An efficient strategy for the synthesis of pharmaceutically important and synthetically useful cyanoimines, as well as cyanamides, has been described. This strategy is enabled by dual photoredox/copper-catalyzed cyanation of O-acyl oximes or O-acyl hydroxamides. This state of the art protocol for cyanoimines and cyanamides features readily available starting materials, mild reaction conditions, good functional group tolerance, and operational simplicity. The resultant cyanoimines can be transformed into structurally diverse and functionally important N-containing heterocycles.
