Abstract

Sposób otrzymywania 2,2'-bibenzimidazolu o wzorze 1 w reakcji fenyleno-1,2-diaminy z kwasem szczawiowym polega na tym, że reakcję prowadzi się w glikolu dietylenowym lub trietylenowym bez konieczności wydzielania produktu pośredniego.The method of obtaining 2,2'-bibenzimidazole of the formula I by reacting phenylene-1,2-diamine with oxalic acid is based on the fact that the reaction is carried out in diethylene or triethylene glycol without separating the intermediate.
