英文摘要 | Intramolecular methyl migration in the protonated N,N '-dimethylpropane-1,3-diamine and N,N'-dimethylethane-1,2-diamine were studied by tandem mass spectrometry. Using density function theory at B31yp/6-31g (d) level, intramolecular S(N)2 methyl migration in the protonated N,N'-dimethylpropane-1,3-diamine and N,N'-dimethylethane-1,2-diamine were found to proceed by a high-energy inversion mechanism or by a high-energy retention mechanism. With the number of bond between two nitrogen atoms in diamine increasing, the inversion mechanism becomes more favorable. (c) 2007 Elsevier B.V. All rights reserved. |
