with bases have been systematically examined. Monomeric C-methoxy-imines are available from some of these reactions. C-methoxyphenacylarylamines, made by two routes, were converted into monomeric imines on treatment with noble-metal catalysts. The boron trifluoridecatalysed reactions of aryl aldehydes with sulphonamides provide a new and convenient route to N-sulphonylarylimines.
已经系统地检查了N-甲苯磺酰基苯甲胺与碱的合成和反应。单体C-甲氧基亚胺可从这些反应中的一些获得。在贵金属催化剂处理下,通过两种途径制得的C-甲氧基苯甲酰基芳基胺被转化为单体亚胺。芳基醛与磺酰胺的三氟化硼催化反应为制备N-磺酰基芳烃提供了新的便捷途径。
