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: MBH.sub.4-n-a (R*).sub.n (R').sub.a ; MBH.sub.2-b (R**) (R').sub.b ; MBH(R***); MBH(R*) (R"); MAlH.sub.4-n-a (R*).sub.n (R').sub.a ; MAlH.sub.2-b (R**)(R').sub.b ; MAlH(R***); and MAlH(R*) (R"), wherein M is Na.sup.+, Li.sup.+ or K.sup.+ ; 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.ltoreq.3, and with the further proviso that when R** is S-BINOL, M is not Li.sup.+.
描述了新颖的手性硼和铝氢化物配合物,包括手性氢化物配合物的组成,以及它们的合成和使用方法。这些新颖的手性氢化物配合物的化学式为:MBH.sub.4-n-a (R*).sub.n (R').sub.a ; MBH.sub.2-b (R**) (R').sub.b ; MBH(R***); MBH(R*) (R"); MAlH.sub.4-n-a (R*).sub.n (R').sub.a ; MAlH.sub.2-b (R**)(R').sub.b ; MAlH(R***); 和 MAlH(R*) (R"),其中M为Na.sup.+、Li.sup.+或K.sup.+;每个R*独立地是一种单齿手性配体;R**是一种双齿手性配体;R***是一种三齿手性配体;R'是一种单齿不手性配体;R"是一种双齿不手性配体;n为1-3;a为0-2;b为0-1,但需满足n+a≤3的条件,并进一步规定当R**为S-BINOL时,M不是Li.sup.+。
