An eth sol of Lithium Boroazide, L1B(N,)4 is formed in 90% yield upon evapn to dryness of a reaction mixt consistg of excess HNa in eth soln and frozen L1BH4 in eth soln. The wh solid residue is an expl very sensitive to pressure and to percussion. It is sol in eth and easily hydrolyzed. B(Na)j and LiNa are assumed to be intermediate products (Ref 1)... 

The chem reaction between LiNa and benzene diazonium chloride has been described by Huisgen (Ref 20). The formation of an exp I Lithium Boroazide, LiB(N3)4, a wh solid sol in ether, easily hydrolyzed and very sensitive to impact and pressure was reported by Wiberg Michaud (Ref 19). This compd was obtd on evapg to dryness a mixt of ether solns of excess HN, and LiBfi, Li azide and B azide were assumed as intermediate products in the stepwise reaction...
