Synergistic effect of hydrogen bonds and π-π interactions of B(C6F5)3·H2O/amides complex: Application in photoredox catalysis

open access: yesiScience, 2023
Summary: B(C6F5)3·H2O has been long recognized as a common Brønsted acid. The lack of X-ray crystal structure of B(C6F5)3·H2O with other substrates has greatly limited the development of a new catalytic mode.
