制备了新型苯并咪唑磺酸盐，并对其进行了表征。它们被原位与[RuCl2（对伞花烃）](2)结合，生成了高效的催化体系，在120摄氏度的整洁条件下，在叔丁酸钾的存在下，将伯芳胺选择性地n -烷基化成仲胺。(C) 2015 Elsevier B.V.版权所有
New benzimidazolium sulfonate salts have been prepared and fully characterized. They have been associated in situ with [RuCl2(p-cymene)](2) to generate efficient catalytic systems operating at 120 degrees C under neat conditions in the presence of potassium tert-butylate for selective N-alkylation of primary aromatic amines into secondary amines.
