DEHYDROGENATION CATALYST, AND CARBONYL COMPOUND AND HYDROGEN PRODUCTION METHOD USING SAID CATALYST

摘要

Objects of the present invention are to provide a novel dehydrogenation reaction catalyst, to provide a method that can produce a ketone, an aldehyde, and a carboxylic acid with high efficiency from an alcohol, and to provide a method for efficiently producing hydrogen from an alcohol, formic acid, or a formate, and they are accomplished by a catalyst containing an organometallic compound of Formula (1).;
