The next chapter of our metal catalysis work is now on ChemRxiv. We report that an unusual reversible Pd "ring-walking" process can be used to access unconventional isomers of cross-coupling products! doi.org/10.26434/chemr…

Sharing some work on organic sulfenyl fluorides (R-S-F) in this preprint: go.shr.lc/4aTUeYh. R-SF3 and R-SF5 are well-known functional groups, so why do we never hear about their baby cousin R-SF? Would such a thing behave like R-SCl or R-SBr?

An expanded version of this work is now out in J. Am. Chem. Soc.: doi.org/10.1021/jacs.4… Many thanks to several fantastic reviewers who guided us to improve the study (incl discovery of a new ligand for less biased p-alkyl/aryl substrates). Happy Holidays!

Our group reports a Ni-catalyzed desulfurative ring contraction method in J. Am. Chem. Soc.. By performing double SNAr reactions and "deleting" the sulfur atom afterwards, many fun heterocycles can be synthesized in 2 steps from commercial materials. Congratulations, Jianhan (Johnson) Zhou!
