The present invention relates to a process for the preparation of α-chloroketones from readily available alkyl esters by the reaction of a sulfoxonium ylide on said alkyl esters to generate a keto sulfoxonium ylide that is in turn treated with anhydrous HCl.
The utility of gold catalysis for carbene X-H bond insertion chemistry is described for the first time, taking advantage of the unique reactivity of sulfoxonium ylides as metal carbene precursors. (C) 2010 Elsevier Ltd. All rights reserved.
