I2O5as a mild, inexpensive, and environmentally benign oxidant for the α -thiocyanation of ketones

α-Selective C(sp3)-H Thio/Selenocyanation of Ketones with Elemental Chalcogen

A facile method is disclosed for the synthesis of α-thio/selenocyanato ketones through regioselective C-H thio/selenocyanation of ketones. The advantages include the use of easily available starting materials, high efficiency, simple operation, and easy scale-up. Control experiments provide evidence that the reaction proceeded via a radical way, while kinetic isotope effect experiments reveal that the cleavage of the C-H bond serves as the rate-limiting step.

Selenocyanobenziodoxolone: a practical electrophilic selenocyanation reagent and its application for solid-state synthesis of α-carbonyl selenocyanates

A solvent- and oxidant-free solid state synthetic methodology for the synthesis of α-carbonyl selenocyanates is developed.

Graphene oxide: a promising carbocatalyst for the regioselective thiocyanation of aromatic amines, phenols, anisols and enolizable ketones by hydrogen peroxide/KSCN in water

Graphene oxide as a heterogeneous carbocatalyst catalyzes the direct thiocyanation of a variety of arenes and enolizable carbonyl compounds.
