of methods have been proposed for the modification of the Ritter reaction. However, many of these methods involve the use of strongly acidic conditions, stoichiometric amounts of reagents, harsh reaction conditions and extended reaction times. Therefore, the development of mild, efficient, convenient and benign reagents for the Ritter reaction is desirable. In this research, we have developed a clean
已经提出了许多用于改变Ritter反应的方法。然而,许多这些方法涉及使用强酸性条件,化学计量的试剂,苛刻的反应条件和延长的反应时间。因此,需要开发用于Ritter反应的温和,有效,方便和良性的试剂。在这项研究中,我们开发了一种清洁环保的方案,在无溶剂的条件下,使用二氧化硅键合的N-丙基氨基磺酸(SBNPSA)作为催化剂,使用不同的苄醇或叔醇和不同的腈来合成酰胺高产。 开发了一种清洁环保的方案,用于在无溶剂条件下以二氧化硅键合的正丙基氨基磺酸(SBNPSA)为催化剂,通过使用不同的苄醇或叔醇和不同的腈以高收率合成酰胺。
