The scope of the reaction also extends to carbon-based nucleophiles. The reaction relies on the use of 1-bromo-3,3-dimethyl-1,3-dihydro-1\u03bb<sup>3<\/sup>[<em>d<\/em>][1,2]iodaoxole, which provides a key \u03b1-brominated carbonyl intermediate. The reaction mechanism has been studied experimentally and by DFT, and we propose formation of an unusual enolonium intermediate with a halogen-bonded bromide.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Find a list of publications by&nbsp;NordCO<sub>2<\/sub>&nbsp;members on our&nbsp;<a href=\"https:\/\/site.uit.no\/nordco2\/publications\/\">Publications<\/a>&nbsp;page&nbsp;\ud83d\ude42<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Title:An Expedient Method for the Umpolung Coupling of Enols with Heteronucleophiles Abstract:In this paper, we present an unprecedented and general umpolung protocol that allows the &hellip;<\/p>\n","protected":false},"author":514,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"image","meta":{"ngg_post_thumbnail":0,"footnotes":""},"categories":[8],"tags":[],"class_list":["post-2924","post","type-post","status-publish","format-image","hentry","category-research","post_format-post-format-image"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.8 -
