摘要
By adding a small amount of HMPA approximately 2.5 equivalent or ca. 8.1 wt% H(2) can be released from the LiAlH(4)-LiNH(2) mixture at ambient temperature, which is similar to 370 degrees C lower than the corresponding solid-state dehydrogenation. NMR characterizations reveal the formation of intermediates, such as [AlH] and [AlN] species, during the dehydrogenation. LiNH(2) induces the enrichment of [AlH] species in the liquid phase which further reacts with LiNH(2) to produce H(2), Li(2)NH and Al.
