Application

Lithium borohydride solution (2M in THF) has been used for the reduction of 5-benzylidene-2,4-thiazolidinediones and 5-benzylidene-4-oxo-2-thiazolidinethiones to form 5-benzyl-2,4-thiazolidinediones and 5-benzyl-4-oxo-2-thiazolidinethiones, respectively.
Reactant for:
  • Preparation of gallium, indium, rhenium and zinc tris(mercaptoimidazolyl)hydroborato complexes
  • Mechano-chemical metathesis reactions
  • Noncatalytic hydrolysis for hydrogen generation
  • Growth of large gold monolayer protected-clusters
  • Anion substitution reactions
  • Dehydrogenation reactions

The addition of catalysts to complex hydrides is aimed at enhancing the hydrogen absorption desorption properties. Here we show that the addition of carbon nanostructure C60 to LiBH4 has a remarkable catalytic effect, enhancing the uptake and release of hydrogen.

In this paper, ammine lithium borohydride (LiBH(4)·NH(3)) was successfully impregnated into multi-walled carbon nanotubes (CNTs) through a melting technique. X-ray diffraction, scanning electron microscopy, Brunauer-Emmett-Teller, and density measurements were employed to confirm the formation of the nanostructured LiBH(4)·NH(3)/CNTs composites. As

For solid-phase peptide synthesis, 2,4-dimethoxy-4'-hydroxbenzhydrol linker was prepared via lithium borohydride reduction of 2,4-dimethoxy-4'-hydroxybenozophenone. The potassium salt of the linker was coupled to chloromethylpolystyrene. This method proved to be better than use of the cesium salt. This new synthesis gave
