Deoxygenative Borylation of Secondary and Tertiary Alcohols [PDF]

open access: yesAngewandte Chemie - International Edition, 2019
AbstractTwo different approaches for the deoxygenative radical borylation of secondary and tertiary alcohols are presented. These transformations either proceed through a metal‐free silyl‐radical‐mediated pathway or utilize visible‐light photoredox catalysis. Readily available xanthates or methyl oxalates are used as radical precursors.
