DOI: 10.1002/hlca.202500009
Abstract: We report two catalytic enantioselective borylation/oxidation sequences that streamline access to either enantioenriched 1,2‐ or 1,3‐diols starting from O‐benzyl‐protected allylic alcohols as a single precursor. The approach takes advantage of the complementary regioselectivity of the… read more here.

DOI: 10.1021/acs.inorgchem.2c01325
Abstract: Iron-hydride and iron-boryl complexes supported by a pyrrole-based pincer ligand, tBuPNP (PNP = anion of 2,5-bis(di-tert-butylphosphinomethyl)pyrrole), were employed for a detailed mechanistic study on the hydroboration of internal alkynes. Several novel complexes were isolated and… read more here.
