Sažetak
Amidoboranes, a family of B, N-containing compounds that are under a vivid consideration as potential chemical hydrogen containers, can be readily prepared by ball milling from ammonia borane and corresponding hydride(s). However, details of the mechanistic pathways toward these materials are still not satisfactory recovered. By recovering the intermediates and other crucial elements of the synthesis, in-situ and real-time monitoring, by means of Raman spectroscopy and powder XRD, of uninterrupted mechanochemical preparations provides a unique insight into the mechanistic pathways. Here we illustrate the application of these techniques to preparation of several single- and bimetallic amidoboranes. This approach allowed realtime observation of key intermediate phases and a straightforward follow-up of the progress of the reaction, thus enabling a detailed interpretation of mechanistic pathways. On the other hand, from the application point of view, it is crucially important to recover the mechanisms of solid-state thermally-induced decomposition of the obtained amidoboranes. Again, a number of techniques that enable in-situ monitoring of the relevant processes are applied. Here, these efforts will be presented, together with our ongoing results.
