Versuchsvorschrift
20 g (39 mmol) of tris(pentafluorophenyl)borane together with 150 ml of toluene are placed in a reaction vessel and the mixture is subsequently heated 100° C. 1.8 ml (97.5 mmol) of water in 40 ml of toluene are subsequently added dropwise to this solution over a period of 30 minutes. The mixture is subsequently stirred for another two hours at 100° C. After this time, the solvent is taken off in an oil pump vacuum. The residue does not have to be purified further. This gives 12.6 g (89%) of colorless bis(pentafluorophenyl)hydroxyborane. The boroxin content is 5%. 1H-NMR(C6D6, 400 MHz): −133.1 (m, 4 F, o-B(C6F5)2), −147.9 (m, 2 F, p-B(C6F5)2), −161.1 (m, 4 F, m-B(C6F5)2) ppm.
