Tungsten-based compounds (e.g., H 2 WO 4) have been widely utilized in cutting the C―C bond inside cellulose for the production of C 2 products such as ethylene glycol. Hence, combining a tungsten-based compound with an active metal that enables hydrogenolysis of C―OH bonds will be expected to succeed in catalyzing the one-pot …
