It is shown by low-temperature 1H and 19F nuclear magnetic resonance (n.m.r.) spectroscopy that boron trifluoride monohydrate is formed in dilute solutions in acetone containing both water and BF3. In solutions in which [H2O] < [BF3], proton–fluorine coupling is observed which definitely establishes that in acetone solution at low temperatures the monohydrate is the simple donor–acceptor complex H2O → BF3. In solutions in which [H2O] > [BF3], no proton–fluorine coupling was observed because of rapid proton exchange.
