Cytosine derivatives form hemiprotonated dimers in solution and the gas phase
Abstract
Hemiprotonated dimers of cytosine derivatives, implicated in the formation of the i-motif of DNA, have been created in solution and the gas phase. The mechanism of dimerization has been analyzed by mass spectrometry and multidimensional NMR spectroscopy.
