congener have been synthesized and demonstrated to provide access to type II anion relay chemistry (ARC) through a fundamentally new mechanistic pathway. Similar to previous studies, but contrary to initial hypothesis, Brook rearrangement additives (hexamethylphosphoramide and CuI) are necessary to promote Si migration and anion capture.
截然不同:两种 1-氧杂-2-硅杂环戊烯和一种饱和同系物已被合成,并被证明可以通过一种全新的机制途径提供 II 型阴离子中继化学 (ARC)。与之前的研究类似,但与最初的假设相反,Brook 重排添加剂(六甲基磷酰胺和 CuI)对于促进 Si 迁移和阴离子捕获是必要的。
