Bond-forming reactions of molecular dications as a new route to polyaromatic hydrocarbons.
Mass-selected CmHn2+ dications of medium size (m = 6-14, n = 6-10) undergo bond-forming reactions in the presence of acetylene with Cm+2Hn2+ + H2 as the major product channel. These unprecedented reactions of organic dications offer a feasible route for the formation of polycyclic aromatic hydrocarbons under extreme conditions, such as in interstellar clouds.
