Direct alpha-oxytosylation of ketones by using pentavalent organobismuth reagents
A new method for the preparation of alpha-tosyloxy ketones by a direct oxytosylation of ketones using a combination of heterocyclic pentavalent organobismuth compounds and p-toluenesulfonic acid monohydrate is described.
