Selective functionalizations of aryl C-H bonds in 2-arylpyridines have been developed via sequential borylation and aerobic oxidative copper catalysis, and the corresponding aryl halides, sulfones, azides and arylamines were obtained in good yields. The protocol uses cheap and readily available boron tribromide (BBr3) as the borylating reagent, and inorganic salts (potassium iodide, ammonium bromide, sodium alkylsulfinates, sodium azide) as the functional group sources. This method makes functionalizations of aryl C-H bonds easy. Copyright
Synthesis of the New Pyridobenzo-v-triazinium System via Valence Bond Isomerization

α-Pyridylphenyl diazonium salts 2 were found to undergo valence bond isomerization and gave the new pyridobenzo-v-triazinium salts 3.The ir and nmr studies on the products showed that isomers 2 and 3 form an equilibrium, and the ring closure is favoured by electron withdrawing substituents.
