Conclusions
-
1.
The stable monohydride complexes NaAlHAm3, where Am=N(C2H5)2, NC5H10, and NC5H6, were detected by27Al NMR in the reactions of NaAlH4 with diethylamine, piperidine, and pyridine in THF solutions.
-
2.
The corresponding tri- and dihydride complexes NaAlH3Am and NaAlH2Am2 are unstable in solution and disproportionate partially or completely to NaAlH4 and NaAlHAm3.
-
3.
When diisopropylamine is reacted with NaAlH4 in THF, no more than 2 moles of the amine react, and the stable tri- and dihydride complexes NaAlH3N(i-C3H7)2 and NaAlH2[N(i-C3H7)2]2form.
