摘要：
(Chemical Equation Presented) A nitrous acid complex was identified by spectroscopic and kinetic analyses under stopped-flow conditions as an intermediate in the reaction of copper(I) nitrite complex 1 with trifluoroacetic acid (see scheme). A reaction mechanism was proposed in which two protons are transferred in a stepwise manner to the nitrite anion. Intramolecular electron transfer from copper to the nitrite ligand occurs in the second protonation step. © 2006 Wiley-VCH Verlag GmbH & Co. KGaA.
