METHOD FOR ACTIVATING ACTIVE HYDROGEN AND ACTIVATION CATALYST

Title:

METHOD FOR ACTIVATING ACTIVE HYDROGEN AND ACTIVATION CATALYST

Document Type and Number:

WIPO Patent Application WO/1999/058242

Kind Code:

A1

Abstract:

An activation catalyst wherein at least one of the atoms which constitute a functional group has an ESPD charge in the range of -0.65 to -1.05 (electrons) or an activation catalyst which has a cyclic quaternary ammonium salt, as a functional group, wherein the nitrogen atom constituting the ammonium salt has an ESPD charge in the range of +0.4 to +1.3 (electrons). Such a catalyst can activate with efficiency an active hydrogen of a compound, utilizing the atom having an ESPD charge in the above-mentioned range as an active site. That is, the catalyst is suitable as an activation catalyst in various reactions accompanying activation of a hydrogen atom in a molecule of a reactant. Further, a reaction excellent in selectivity can be carried out with the catalyst.
