Reaction of NaGaH4 with alcohols

A reversible hydrogen storage mechanism for sodium alanate: the role of alanes and the catalytic effect of the dopant

“…According to the proposed mechanism, this is consistent. Reactions (4) and (5) hold NaH to a very low concentration during Phase 1 [3,4,6,9]. NaH is not seen early on in the XRD data.…”

“…This decomposition process recently has been suggested from an analysis of decomposition temperatures for various complex metal hydride materials [32]. The NaH can react with NaAlH 4 and eventually produce Na 3 AlH 6 by another reactive encounter with a second NaH [3,4,6,7,9]. The first consumption of NaH produces a material with the stoichiometry [Na 2 AlH 5 ], a simple addition reaction of NaH with NaAlH 4 [9].…”

Interaction of the [GaH4]− Anion with Weak XH Acids − A Spectroscopic and Theoretical Study

“…[27] The same is true of the aminolysis reactions. The reaction can stop at the first step of DHB intermediate formation, depending on temperature and the amount and strength of the proton donor.…”

“…We have not yet studied this process in more detail, but there are many examples of boron hydride alcoholysis/hydrolysis studies in the literature, e.g. the BH 4 Ϫ /R f OH [26] and GaH 4 Ϫ /ROH [27] systems. However, the H···H bonding was not considered as an intermediate along the reaction pathway.…”

“…[27] However, a special study is necessary in order to obtain the data corresponding to the spectroscopic changes during the alcoholysis/aminolysis reactions and definite assignment of each band. Ϫ .…”
