Herein, we describe a novel transition metal-free, umpolung strategy for the α-arylation of
ketones by capturing transient oxyallyl cations with arylboronic acids. A variety of α-arylated …

We report the synthesis of bis-quaternary centers at the α-positions of cyclohexanones. In
this chemistry, ionization of an α-hydroxy allyl vinyl ether with Cu (MeCN) 4 BF 4 catalyst at …

Nucleophilic addition to the oxy‐allyl cation intermediate has emerged as a promising
methodology for functionalization of the α‐position of carbonyl compounds in an umpolung …

1. Purpose The purpose of this research discussion is to first carry out a literature review on
the discovery and utility of oxyallyl cation intermediates. Oxyallyl cation intermediates …
