Hazard Predictions

• Flammable: Reaction products may be flammable
• Generates gas: Reaction liberates gaseous products and may cause pressurization
• Toxic: Reaction products may be toxic

Depending on the conditions, sodium borohydride (NaBH4) can reduce anhydrides to lactones (in the case of succinic anhydride), alcohols, ethers, or alkanes, at or below room temperature. Lithium aluminum hydride (LiAlH4) can also perform some of these reductions (Kammermeier, B. 2000. Reduction. Ullmann's Encyclopedia of Industrial Chemistry. (Online)).

Lithium borohydride, lithium aluminum hydride, and some other complex hydrides can reduce anhydrides in a similar reaction to that of complex hydrides with acid halides. The likely products of this reaction are aldehydes and alcohols (Rittmeyer, P., U. Wietelmann. 2002. Hydrides. Ullmann's Encyclopedia of Industrial Chemistry. Wiley-VCH Verlag GmbH & Co. KGaA. (Online); Eggeman, T. 2001. Hydrides. In Kirk-Othmer Encyclopedia of Chemical Technology. John Wiley & Sons, Inc. (Online)).
