DOI: 10.1007/3458
Abstract: This microreview covers data regarding the synthesis of 1,3-dihydro-2 H -benzimidazol-2-ones published during the last five years. The synthetic routes to benzimidazolones can be classified into several types: cyclocarbonylation of 1,2-diaminobenzenes, transformation of benzimidazolium salts,… read more here.

Abstract: Abstract Two new organic compounds composed of 8-hydroxyquinoline and benzimidazol-2-one units have been successfully prepared, and identified by different spectroscopic methods (IR, NMR and Elemental analysis). The synthesized heterocyclic namely 1-((8-hydroxyquinolin-5-yl)methyl)-3-(prop‑1-en-2-yl)-1H-benzimidazol-2(3H)-one (HMPB) and 1,3-bis((8‑hydroxy-quinolin-5-yl)methyl)-1H-benzimidazol-2(3H)-one (BHMB)… read more here.

DOI: 10.1039/c8nj03166e
Abstract: A practical iodine-mediated direct aromatic C–H amination reaction has been established for benzimidazol-2-one synthesis under transition-metal-free conditions. The required 1,3-diarylurea substrates are readily accessible by the addition of N-substituted arylamines to the corresponding isocyanates. This… read more here.
