The hydrolysis of imidazolinium chlorides takes place readily in a basic water/dichloromethane biphasic mixture at room temperature. Experimental conditions were optimized to afford full conversions and high yields of γ-aminoformamides starting from symmetrical or unsymmetrical substrates. Structural parameters that affect the resilience of these important NHC precursors in the presence of moisture
氯化咪唑啉鎓在室温下的碱性水/二氯甲烷双相混合物中很容易发生水解。对实验条件进行了优化,以从对称或不对称底物开始获得完全转化和高产率的γ-氨基甲酰胺。研究了在湿气存在下影响这些重要 NHC 前体弹性的结构参数。特别强调了抗衡阴离子的关键影响。
