Benzoyl Trifluoromethanesulphonate. A Highly Efficient Benzoylating Agent for Sterically Hindered Hydroxyl Groups
Reactions of benzoyl trifluoromethanesulphonate (BzOTf) with a variety of alcohols, including some with sterically hindered secondary and tertiary hydroxy groups, with phenolic compounds, and with 1,2-diols at low temperatures provide the corresponding benzoates in high yield.
Benzoyl Trifluoromethanesulfonate. A Mild Reagent for the Benzoylation of Sterically Hindered Hydroxyls
Benzoyl trifluoromethanesulfonate (BzOTf) is a highly efficient reagent for the benzoylation of a variety of alcohols under mild conditions.These include hindered secondary and tertiary hydroxyls, phenols, and α-glycols.Sensitive functionality is stable when the reaction is performed in the presence of pyridine.Several unique rearrangements of Lewis acidsensitive compounds were also effected.
