Our latest work just appeared in @JournalOrganic ! We found that the rate of the Passerini reaction is significantly enhanced by the addition of a HBD solvents—specifically HFIP. Read more: pubs.acs.org/doi/10.1021/acs… Thanks to all co-authors for the great collaboration!

Strong Hydrogen Bond Donating Solvents Accelerate the Passerini Three-Component Reaction

Abstract. We report enhanced reaction rates of the Passerini reaction (P-3CR) using 1,1,1,3,3,3-hexafluoroisopropanol (HFIP) as a cosolvent. Although alcoh
