Recent Advances in the Catalytic Transformations

This article details the latest progress in synthesizing alkylsulfonyl fluorides through different approaches that utilize photoredox catalysis, electrocatalysis, transition-metal catalysis, and organocatalysis. The alkylsulfonyl fluorides thus prepared could be utilized further in sulfur(VI) fluoride exchange (SuFEx) click reactions.

SuFEx: Sulfonyl Fluorides that Participate in the Next Click Reaction

In collaboration with K. Barry Sharpless and coworkers, we offer a variety of sulfonyl fluoride reagents that undergo a “Click II” reaction.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
