protein–palladium oxidative addition complexes (OACs) that enable catalyst transfer polymerization to furnish protein–polyarene conjugates. These polymerizations occur with electron-deficient monomers in aqueous buffers open to air at mild (≤37 °C) temperatures with full conversion of the protein OAC and an average polymer length of nine repeating units. Proteins with polyarene chains terminated with palladium

method for the synthesis of aryl perfluoroalkanes from arenes and aryl bromides is described. Substituted arenes or aryl bromides are converted in situ to an aryl boronate ester that readily undergoes perfluoroalkylation in air with [(phen)CuRF]. A broad range of aryl bromide substrates were perfluoroalkylated in good yield for the first time. [(phen)CuCF3] is now commercially available and has been prepared

general approach for the synthesis of 3,5‐disubstituted pyridine‐based boronic acid pinacol esters with amino acid side chains in the 3‐position (representing Phe, Leu, Ile, Lys, Asp, Asn) is presented and exploits the functional group tolerance of the Knochel–Grignard reagents. The buildingblocks have been used in a convergent in situ two‐step synthesis of teraryl α‐helix mimetics.
