Generation of the organo-rare gas dications HCCRg(2+) (Rg = Ar and Kr) in the reaction of acetylene dications with rare gases

Abstract

Using doubly ionized acetylene as a superelectrophilic reagent, the new rare-gas compounds HCCAr2+ and HCCKr2+ have been prepared for the first time in hyperthermal collisions of mass-selected C2H22+ with neutral rare gases (Rg).
