摘要：

Multinuclear NMR spectroscopy has been used to study the solution properties of several perfluoroaryl borane derivatives. The information obtained from all the NMR active isotopes present in these molecules made it possible to establish not only chemical identity, structure and dynamics of their reaction products, but also the complexity of the solution speciation. In other words, multinuclear NMR helped in unravelling the real forms in which they are present in solution, that in some cases can change dramatically according to even slight changes of the solution conditions. Examples will be presented related to the chemistry of tris(pentafluorophenyl)borane, B(C6F5)(3), and bis(pentafluorophenyl)borinic acid, B(C6F5)(2)OH. (C) 2008 Elsevier B.V. All rights reserved.
