Pd-NHC catalysed direct sulfenylation and selenylation of 3-iodo-4-quinolones has
been developed. This protocol provides an alternative route for the construction of
ipso-C–S and C–Se bond formation in 4-quinolones under aerobic conditions.
Key words
4-quinolone - Pd-NHC - sulfenylation - selenylation - cross-coupling
