Cyanation of Bronic Acids through Cross-Coupling Reaction

Typical Procedure:
Benzyl thiocyanate, the boronic acid (1.5 eq.), CuTC, and Pd(PPh3)4 (3 mol%) are added into a flask that is then flushed with argon. Dry and degassed 1,4-dioxane is added (2 mL for each 0.1 mmol benzyl thiocyanate). The brown suspension is stirred under argon at 100 ℃ for 12 h. Then Et2O (10 mL) is added and the reaction is washed with sat. NH4Cl followed by sat. Na2CO3 and then brine. After evaporation of the solvent, the residue is purified by preparative plate silica chromatography (hexane : AcOEt = 4 : 1) to give the desired nitrile compound.
