The internal OH group of 1,2‐propanediol is selectively removed in the deoxygenation catalyzed by [{Cp*Ru(CO) 2 } 2 ( μ ‐H)] + OTf − ( 1 , Cp*=C 3 Me 5 , OTf=trifluoromethanesulfonate; see scheme). This reaction provides a model for deoxygenation of polyols derived from carbohydrates, for use in alternative, biomass‐based feedstock applications. An ionic mechanism is proposed that involves the dihydrogen complex [Cp*Ru(CO) 2 ( η 2 ‐H 2 )] + .
