애플리케이션

2-pyridinesulfonyl fluoride can be used for the deoxyfluorination of primary and secondary alcohols in combination with an amidine or guanidine base. In comparison with other common deoxyfluorination reagents, for example, DAST exhibits less elimination side products in direct comparison on certain substrates.

Research in the Doyle group focuses on two areas: nucleophilic fluorination and nickel catalysis. The Doyle group has developed several reagents that advance these research areas. In fluorination, 2-pyridinesulfonyl fluoride (PyFluor) can be used for the mild deoxyfluorination of primary and secondary alcohols, a procedure which is normally accomplished by the sensitive reagent DAST. In nickel catalysis, the Doyle group has developed a modular, air-stable nickel precatalyst, [(TMEDA)Ni(o-tolyl)Cl], which has broad utility for a wide variety of reactions. This precatalyst can be used in place of Ni(cod)2, NiCl2, as well as other reported precatalysts. Doyle has also reported electron-deficient olefin ligands as a new class of ligand for accelerated reductive elimination. In particular, the sultam-derived ligand Fro-DO has been found to be critical for high yields in the cross-coupling of tertiary aziridines to form quaternary centers.
