Hydroxyacetylene: Generation and Characterization of the Neutral Molecule, Radical Cation and Dication in the Gas Phase

The simplest ynol, the title compound 2 , like the singly and doubly positively charged species 3 and 4 , respectively, could be generated in the mass spectrometer. Cleavage of CO from 1 furnished the radical cation 3 , which on neutralization with Xe affords the neutral ynol 2 . The radical cation 3 can be converted into the dication 4 by charge stripping. equation image
