We report the reactivity of new Cβ silylated ketenimines (4, 5, 6) and lithiated-silylated ketenimine 3 leasily generated from lithiated S-methyl-N-phenyl-trimethylsilylethanimidothioate 2] toward electrophilic reagents. Reactions of these ketenimines with strong electrophilic reagents such as sulfanyl chloride (PhSCl) gave access to new sulfanylated ketenimines. With less reactive species [benzenesulfinyl
我们报告了新的Cβ甲硅烷基化的氯胺酮(4、5、6)和锂化的甲硅烷基化的S-甲基-N-苯基-三甲基甲硅烷基亚氨基硫酸酯2 ]容易产生的锂化的甲硅烷基化的酮亚胺3对亲电试剂的反应性。这些烯酮亚胺与强亲电试剂如硫酰氯(PhSCl)的反应使人们获得了新的磺酰化酮亚胺。具有较少的反应性物种[苯磺酰氯(PhS(O)Cl),对甲苯磺酰氯,三甲基卤硅烷,氯磷酸二异丙酯,乙酰氯和环氧丙烷]和3,加成发生在Cβ或氮原子上,分别导致相对不稳定的官能化酮亚胺或新的甲硅烷基化的氨胺。
