“…This is attributed to the decarbonylation reaction, which produces another equivalent of benzyl radicals. 4,5 On longer time-scales, the benzyl radical absorption depletes with second-order kinetics, 6,9,20 when oxygen is excluded. 11 This reaction corresponds to benzyl radical coupling, 2 which is known to be a diffusion-controlled reaction.…”

“…In addition, the benzyl radical can combine with itself or react with H atoms from H + + e s − , limiting the depth from which benzyl can evaporate (Sections S8 and S9). 23 We describe experiments below demonstrating that e s − reacts with BTMA + close enough to the surface to generate benzyl radicals and TMA that escape into the gas phase. The average e s − reaction depth is estimated to be only 20 Å, spanning a distance of roughly two BTMA + molecules.…”
