Reagent for Pd-catalyzed сross-coupling cyanation
Benzyl thiocyanate is a reagent solution to the cyanation problem of aryl nitriles1. It is a shelf-stable solid, with a low melting point (39-41 ℃) and good solubility in diethyl ether, and dioxane2. This reagent is a convenient source for cyanide in a cyanation of boronic acids that is copper(I)-mediated coupling with palladium as a catalyst2. Using this protocol, a variety of nitriles can be easily synthesized: sterically congested substrates, electron-deficient aryl boronic acids, and heteroaryl boronic acids with ease undergo reaction and give good yield2.
Synonyms: (Thiocyanatomethyl)benzene; α-Thiocyanatotoluene; Tropeolin
