Abstract: Simple nucleophiles with structural similarities to known hydroboration catalysts can readily mediate the formation of BH3 and borohydride species from pinacolborane (HBpin). Alkyne and alkene hydroboration reactions were successfully mediated by nucleophiles through BH3 generation,… read more here.

DOI: 10.1021/acs.orglett.4c03591
Abstract: Hidden boron catalysis plagues catalyzed hydroboration reactions, with the “catalyst” acting to mediate the decomposition of HBpin/HBcat to BH3 which is the actual (hidden) catalyst. N,N,N′,N′-Tetramethylethylenediamine (TMEDA) has been used to identify hidden boron catalysis… read more here.
