Chiral hydride complexes

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: PA1 MBH4-n-a (R*)n (R')a ; PA1 MBH2-b (R**) (R')b ; PA1 MBH(R***); PA1 MBH(R*) (R"); PA1 MAlH4-n-a (R*)n (R')a ; PA1 MAlH2-b (R**)(R')b ; PA1 MAlH(R***); and PA1 MAlH(R*) (R"), PAL wherein PA1 M is Na+, Li+ or K+ ; PA1 each R* is independently a monodentate chiral ligand; PA1 R** is a bidentate chiral ligand; PA1 R*** is a tridentate chiral ligand; PA1 R' is a monodentate achiral ligand; PA1 R" is a bidentate achiral ligand; PA1 n is 1-3; PA1 a is 0-2; and PA1 b is 0-1, PAL with the proviso that n+a3, and with the further proviso that when R** is S-BINOL, M is not Li+.

Veretherungen von Diolen, Triolen und Hydroxycarbonsaeurederivaten ueber Thallium(I)-alkoholate. Eine neue Variante der Williamson-Reaktion

The etherifications listed in tables 1 and 2 are achieved by converting hydroxy-derivatives, which contain additional oxygen functions, into thallium(I) alkoxides with thallium ethoxide, and treatment with haloalkanes.The scope and limitations of the method are discussed.
