摘要：
Three orders of magnitude of 1H NMR signal enhancement were observed in the metal-free activation of parahydrogen using an ansa-aminoborane in the presence of a 100-fold water excess at 9.4 T. Kinetic studies corroborated the reversibility of water addition to the intramolecular N-B Lewis centers in both polar and nonpolar solvents. Furthermore, DFT modeling supported these results.
