Enolonium species/iodo(III)enolates of carbonyl compounds have been suggested to be intermediates in a wide variety of hypervalent iodine induced chemical transformations of ketones, including α‐C−O, α‐C−N, α‐C−C, and α‐carbon–halide bond formation, but they have never been characterized. We report that these elusive umpoled enolates may be made as discrete species that are stable for several minutes
AbstractWe used 4-acetyl-3,5-diarylcyclohexanones bearing two different aromaticrings as synthons for the preparation of 6,7-diaryl-4-(dialkylamino)bicyclo[2.2.2]octanones, starting materials for new antiprotozoals. Graphical abstract

Synthetically useful 4-acetonylindoles have been conveniently prepared from 2-alkynylanilines and silyl enol ethers using a dearomatization strategy. The two-step/one-pot protocol involves an iodosylbenzene-mediated oxidative dearomatization and a silver-catalyzed domino reaction.
