The triphenylcyclopropenium chloride, bromide and iodide evaporate in the mass spectrometer mainly as the covalent cation‐halide adduct, the fluoroborate as the corresponding fluoride adduct and boron trifluoride. In addition di‐3,3′‐triphenylcyclopropene is formed, presumably via triphenylcyclopropenyl radicals.
