We report herein the use of the (dihydrido)iron catalyst, Fe­(H)2(dmpe)2, for the selective reduction of CO2 into either bis­(boryl)­acetal or methoxyborane depending on the hydroborane used as a reductant. In a one-pot two-step procedure, the in situ generated bis­(boryl)­acetal was shown to be a reactive and versatile source of methylene to create new C–N but also C–O and C–C bonds.
