Lithium aluminium hydride, use

Secondary aminophosphines are rare, but may be obtained in a straightforward manner, as shown for (57) and (58). The latter are also obtained, together with the tertiary aminophosphines, when (59) are treated with iso-propylmagnesium chloride. [58 R = N(SiMe3)2] has been made independently by Cowley, who also reports (60). Reduction of bis(trimethylsilyl)amino-dichlorophosphine gave either (61) or (62), depending on the amount of lithium aluminium hydride used. Experimental details for the large-scale preparation of (silylamino)phosphines have been published. ... 

Metal hydrides include lithium aluminium hydride used extensively in organic synthesis. They are highly reactive. 

Phenolic (and amine) antioxidants in extracts of PVC have been titrated electrometrically with lithium aluminium hydride, using platinum or silver electrodes. Small amounts of water in the sample or analysis solvent have an influence on the results obtained by these procedures.
