(57) Abstract: An activation method for activating active hydrogen contained in a compound, and an activation catalyst which can be suitably used as a catalyst in various reactions involving activation of active hydrogen contained in the compound. provide. SOLUTION: The activation catalyst has a cyclic quaternary ammonium group as a functional group, and an ESPD charge of a nitrogen atom constituting the ammonium group is +0.4 to +1.3 (elect). rons). Thereby, the catalyst can efficiently activate the active hydrogen of the compound using the nitrogen atom having the ESPD charge in the above specific range as an active site. That is, the catalyst is suitable as an activating catalyst in various reactions involving activation of the active hydrogen. Further, by using the activation catalyst, a reaction excellent in selectivity can be performed. |
