• Reacts with NaBH₄ in ether or THF to give zinc borohydride; Zn(BH₄)₂, which is used in situ as a versatile, non-basic, selective reducing agent. Review: Synlett, 885 (1993). The reactivity of Zn(BH₄)₂ has the advantage of being relatively non-toxic. See, e.g.: Selective reduction of aldehydes in the presence of ketones: Tetrahedron Lett., 31, 7663 (1990).
