[Studies on the gas phase reaction of ablated Ni+ with molecular flows of alcohols in the time-of-flight mass spectrometer].
A apparatus combining molecular flows, laser ablation and time-of-flight mass spectrometer was first designed, in which the gas phase reactions of metal ions with organic compounds were realized. In a small quartz cell of it, laser ablated Ni+ meet and react with molecular flows of alcohols, and their product ions were detected by the time-of-flight mass spectrometer. The gas phase reactions of Ni+ with C2-C6 alcohols were studied. All of which can be explained by the following mechanism: (1) Insertion of Ni+ into bonds of alcohols; (2)Following each insertion, a beta-hydrogen shift onto Ni+ to produce intermediate; (3) Dessociation of each intermediate by loss of neutral molecular to give product ion.
