A green C-H bond activation of azole based bio-pertinent substrates such as benzoxazole, benzothiazole, benzimidazole, etc. are accomplished using readily prepared 1-aryltriazenes RN=NNR1R2 (R = C6H5, 4-CH3C6H4, 4-ClC6H4, etc.; R1 = R2 = Et; R1R2 = -(CH2)5-, -(CH2)2O(CH2)2-) as arylating agent. Under an optimized condition employing Pd(OAc)2 and CuI in either hydrophilic [Bmim][BF4] or hydrophobic [Bmim][PF6] IL medium with [BMIM(SO3H)][OTf] as a promoter, these arylation reactions proceeded smoothly to afford 2-aryl substituted azoles I (X = O, S, NCH3, NC6H5, 4-CH3C6H4N; R3 = H, Me; R4 = H, NH2, Cl, CH3) and 2-(p-tolyl)thiazole in acceptable to better yields besides noticeable functional group tolerance. The prospective for recovery and re-use of ionic liquid solvent is demonstrated.
