Benalil, Aziza published the artcileSynthesis of 1,2-aminoazides. Conversion to unsymmetrical vicinal diamines by catalytic hydrogenation or reductive alkylation with dichloroboranes, SDS of cas: 4584-49-0, the publication is Tetrahedron (1991), 47(38), 8177-94, database is CAplus.
1,2-Aminoazides, e.g., I, are easily prepared from 1,2-amino alcs. Catalytic hydrogenation in the presence of palladium on charcoal or reductive alkylation with dichloroboranes afford with good yields unsym. substituted vicinal diamines.
