Acyclic acid anhydrides are reduced to produce primary alcohols using NaBH4 and its many deriva-tives.2 - In most cases, the reaction gives both the primary alcohol and the carboxylate salt (1 1). Whilst such monoreduction may be desirable in cyclic anhydride chemistry (vide infra), it is inefficient when acyclic anhydrides are reduced. Thus, B2H6 or LAH reductions are the preferred synthetic methods. The reductions of mixed anhydrides, for example carboxylic/diphenylphosphoric or carboxylic/car-bonic anhydrides, produce the primary alcohol from the acyl component. ... 

Other reagents of the pyrophosphate type (anhydrides) have been useful in nucleotide synthesis. 0-Benzylphosphorous 0,0-diphenylphosphoric...
