The cover picture shows a graph of the hydrogen release rate from ammonia–borane dissolved in glyme solutions (left). On the right, the compounds formed during the decomposition of ammonia–borane under these conditions as detected by NMR spectroscopy are depicted. The increase of the hydrogen release rate during the course of the reaction as well as the spectroscopic analysis indicate the presence of a complex process governed by multiple pathways. Similarly to the hydrogen release from solid ammonia–borane and in contrast to the low concentration case, the analysis of the decomposition of ammonia–borane in highly concentrated glyme solutions demonstrates that the diammoniate of diborane (DADB) plays a vital role in the overall decomposition scheme. Details are discussed in the article by F. Mertens et al. on p. 49 ff.
