Benzonitrile → HCID 178418369, compound

Participants

Reaction Steps

As outlined in Scheme 8, benzonitrile is treated with sodium azide and zinc chloride to give 5-phenyltetrazole 14 which is converted to the N-trityl derivative 15 by treatment with triphenylmethyl chloride and triethylamine. The zinc reagent 16 was prepared by treatment with n-butyllithium followed by zinc chloride. Coupling with 4-iodotoluene using the catalyst bis(triphenylphosphine)nickel(II) dichloride gives the biphenyl product 17 in high yield. Treatment with N-bromosuccinimide in refluxing carbon tetrachloride, in the presence of a radical initiator such as benzoyl peroxide or 2,2'-azobisisobutyronitrile (AIBN), gives bromide 18.
