Election Impact Mass Spectra of para-Substituted N-Heteroaryl Benzylamines
摘要:
The 70 eV electron impact mass spectra of some para-substituted N-heteroaryl benzylamines, synthesized through the corresponding Schiff bases, are reported. Typical fragmentation patterns are discussed with the aid of mass analyzed ion kinetic energy spectra and exact mass measurements. The compounds are relatively stable under electron impact, the molecular ion being the base peak or the second most intense ion in the spectra. The dominating breakdown process is the benzylic cleavage, that gives rise to the base peak in some of the investigated compounds and to the second intense peak in others.

A novel Ru(II) complex containing 4-(2-hydroxybenzyl)-3-methyl-5-oxo-2,5-dihydropyrazole-1-carbothioic acid methylamide has been applied as a catalyst for directly aminating alcohols. Preliminary investigation on the reaction mechanism has been done with the help of NMR spectroscopy recorded for regenerated catalysts and an NMR reaction. In addition, a plausible mechanism for the formation of the coupled
