Rates of hydride abstraction from amines via reactions with ground-state silver(+) and copper(+)

摘要: Rates of reaction ground-state Ag{sup +} and Cu{sup with mono- (MMA), di- (DMA), trimethylamine (TMA) were measured. In all cases except monomethylamine the reactions found to be fast bimolecular ones. The values are 2.1, 1.7, 1.5 {times} 10{sup {minus}9} cm{sup 3} s{sup {minus}1} for MMA, DMA, TMA, respectively, 1.6 1.4 {times}10{sup 3}s{sup DMA respectively. products amine ions a hydrogen atom removed. channel MMA is endothermic, an association complex product reaction. observed rates in reasonably good accord predictions parametrized trajectory calculational method.
