Anion Relay Chemistry: Access to the Type II ARC Reaction Manifold through a Fundamentally Different Reaction Pathway Exploiting 1‐Oxa‐2‐silacyclopentanes and Related Congeners

Abstract

Distinctly different: Two 1-oxa-2-silacyclopentenes and a saturated 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.
