摘要:Novel chiral boron and aluminum hydride complexes, compositions comprising the chiral hydride complexes, and methods for their synthesis and use are described. The novel chiral hydride complexes are of the formulas: MBH4-n-a(R*)n(R')a; MBH2-b(R**) (R')b; MBH(R***); MBH(R*) (R''); MAlH4-n-a(R*)n(R')a; MAlH2-b(R**)(R')b; MAlH(R***); and MAlH(R*) (R''), wherein M is Na+, Li+ or K+; each R* is independently a monodentate chiral ligand; R** is a bidentate chiral ligand; R*** is a tridentate chiral ligand; R' is a monodentate achiral ligand; R'' is a bidentate achiral ligand; n is 1-3; a is 0-2; and b is 0-1, with the proviso that n+a
