In this study, we investigate the reactivity of [B₁₂X₁₁]^- (X = Br, I) with a series of hydrocarbons in two environments: (1) in the gas phase, using ion-molecule reactions and collision-induced dissociation (CID), and (2) at vacuum/solid interfaces, via fragment ion deposition onto surface layers of reagents. In the gas phase, <i>n-</i>alkyl groups of hydrocarbons are bound to [B₁₂X₁₁]^- via the substitution of a proton by the electrophilic vacant boron atom. However, hydrocarbons with double and triple bonds areThe journal of physical chemistry.
