Nontoxic and inexpensive K4[Fe(CN)6] is first introduced as a cyanating agent to cyanation of arylboronic acids. The present method is simple, practical, and allowed a wide range of substrates including functionalized phenylboronic acids, 1-naphthylboronic acid as well as heterocyclic boronic acids to be smoothly converted into the corresponding products in moderate to high yields.

6 ]. -The method avoids the use of a non-toxic cyanide source and metal catalysis. Extremely poor selectivity (8% GC yield) is observed for α-chloroethylbenzene, whereas no reaction takes place in the case of allylic chlorides. -(REN, Y.; DONG, C.; ZHAO, S.; SUN, Y.; WANG*, J.; MA, J.; HOU, C.; Tetrahedron Lett. 53 (2012) 23, 2825-2827, http://dx.
