Coenzyme F430 from methanogenic bacteria: methane formation by reductive carbon–sulphur bond cleavage of methyl sulphonium ions catalysed by F430 pentamethyl ester

The nickel(I)-form of coenzyme F430 pentamethyl ester is an efficient catalyst for the reductive cleavage of methyl sulphonium salts to methane and thioethers.
