Özet:

 

Many benzimidazole salts bearing a 3-phenylpropyl   substituent (1a-1h) were synthesized and their structures   were identified by 11^{1}H NMR, 1313^{13}C NMR, and IR spectroscopic methods   and elemental analysis. These N-heterocyclic carbene (NHC) precursors were   used as a part of a catalytic system including Pd(OAc)22_{2} and the base in   the Suzuki--Miyaura cross-coupling reaction under microwave irradiation.   They were also used as catalysts in the cyclotrimerization of phenyl   isocyanate to yield 1,3,5-triphenyl-1,3,5-triazinane-2,4,6-trione. It has   been observed that benzimidazole salts made a positive contribution to both   catalytic reactions as a NHC precursor.
