Kinetic Analysis of Aromatic Photocyanation: Naphthalene, Biphenyl, and Phenanthrene

Nucleophilic photocyanation of the unsubstituted aromatic hydrocarbons, naphthalene, biphenyl, and phenanthrene, in both dry and aqueous acetonitrile can be described by a mechanism involving two photoinduced transients.The primary step of the mechanism is the formation of a transient ionic complex through triplet excimer of aromatic hydrocarbon or, when an electron acceptor is present, through triplet exciplex.The attack of cyanide ion on the transient complex yields the cyanated radical, ArHCN., which in aqueous acetonitrile reacts with itself to yield cyano- and dihydrocyano-products or, in dry acetonitrile after being attacked by an electron, is oxidized to the cyano-product.The rate constants for the formation of radical ions and the attack of cyanide ion are calculated from the experimental results.

A cyanide-free aromatic cyanation was developed that uses nitromethane as a cyanide source in water with an amphiphilic polystyrene poly(ethylene glycol) resin-supported palladium catalyst and an alkyl halide (1-iodobutane). The cyanation proceeds through the palladium-catalyzed cross-coupling of an aryl halide with nitromethane, followed by transformation of the resultant (nitromethyl)arene intermediate into a nitrile by 1-iodobutane.

A new source of “CN” employing formamide and cyanuric chloride is introduced for the cyanation reactions. The treatment of formamide and 2,4,6-trichloro-1,3,5-triazine (TCT; cyanuric chloride) afforded an efficient cyanating agent which it can be used as a nontoxic, readily available, and non-expensive reagent in the cyanation transformations. In this study, palladium-catalyzed cyanation of aryl halides was successfully accomplished using this new “CN” source in high yields.
