Oxidative chalcogenation reaction using molybdenum(V) reagents provides fast access
to a wide range of nonsymmetric aryl sulfides and selenides. The established protocol
is tolerated by a variety of labile functions, protecting groups, and aromatic heterocycles.
In particular, when labile moieties are present, the use of molybdenum(V) reagents
provides superior yields compared to other oxidants.
