## Abstract Various 2βarylbenzimidazoles were synthesized from phenylenediamines and aromatic aldehydes __via__ a oneβstep process in the presence of a catalytic amount of a cobaltβsalen complex supported on activated carbon [CoxOβCo(salen) **11**] at room temperature. The salient features of this
Acetylation of various alcohols and phenols was performed successfully using an immobilized cobalt(II) catalyst in high yield. The catalyst shows high thermal stability and was also recovered and reused at least 10 times without any considerable loss of activity.
