Díaz-Urrutia and Ott (Reports, 22 March 2019, p. 1326) report a selective conversion of methane to methanesulfonic acid that is proposed to occur by a cationic chain reaction in which CH3 + adds to sulfur trioxide (SO3 ) to form CH3 –S(O)2 O+ . This mechanism is not plausible because of the solvent reactivity of CH3 + , the non-nucleophilicity of the sulfur atom of SO3 , and the high energy of CH3 –S(O)2 O+ .
