A simple, efficient, mild, and regioselective method for oxyiodination of carbonyl compounds has been reported by using NH4I as the source of iodine and Oxone® as an oxidant. Various carbonyl compounds such as aralkyl ketones, aliphatic ketones (acyclic and cyclic), and β-keto esters proceeded to the respective α-monoiodinated products in moderate to excellent yields. Unsymmetrical aliphatic ketones

Derivatives of indan-1-one and 3,4-dihydronaphthalen-1(2H)-one bearing hydroxy or methoxy substituent on the aromatic ring were efficiently iodinated regioselectively at the α carbonyl position using elemental iodine activated by 1-chloromethyl-4-fluoro-1,4-diazoniabicyclo[2.2.2]octane bis(tetrafluoroborate) (Selectfluor™ F-TEDA-BF4) in methanol.
A satisfactory yield one-pot synthesis of various alpha-mono iodoketones 2 was achieved by iodination under oxidative conditions of ketones 1. The monoiodination of different aliphatic or cyclic ketones (1-tetralones) showed the quite general applicability of the method. (C) 2000 Elsevier Science Ltd. All rights reserved.
