In carbon dioxide utilization by cyclometalated five-membered ring products, the following compounds are used in four types of applications: 1. 2-Phenylpyrazole iridium compounds, pincer phosphine iridium compounds and 2-phenylimidazoline iridium compounds are used as catalysts for both formic acid production from CO and H, and hydrogen production from the formic acid. This formic acid can be a useful agent for H production and storage for fuel cell electric vehicles. 2. Other chemicals, , dimethyl carbonate, methane, methanol and CO, are produced with dimethylaminomethylphenyltin compounds, pincer phosphine iridium compounds, pincer phosphine nickel compound and ruthenium carbene compound or 2-phenylpyridine iridium compounds, and phenylbenzothiazole iridium compounds as the catalysts for the reactions with CO. 3. The five-membered ring intermediates of cyclometalation reactions with the conventional substrates react with carbon dioxide to afford their many types of carboxylic acid derivatives. 4. Carbon dioxide is easily immobilized at room temperature with immobilizing agents such as pincer phosphine nickel compounds, pincer phosphine palladium compounds, pincer ,-dimethylaminomethyltin compounds and tris(2-pyridylthio)methane zinc compounds.
在环金属化五元环产物对二氧化碳的利用中，以下化合物用于四种类型的应用：1. 2-苯基吡唑铱化合物、钳形膦铱化合物和2-苯基咪唑啉铱化合物用作由CO和H生产甲酸以及由甲酸生产氢气的催化剂。这种甲酸对于燃料电池电动汽车的氢气生产和储存可能是一种有用的试剂。2. 其他化学品，如碳酸二甲酯、甲烷、甲醇和CO，是用二甲基氨基甲基苯基锡化合物、钳形膦铱化合物、钳形膦镍化合物和钌卡宾化合物或2-苯基吡啶铱化合物以及苯基苯并噻唑铱化合物作为与CO反应的催化剂来生产的。3. 与传统底物发生环金属化反应的五元环中间体与二氧化碳反应，生成多种类型的羧酸衍生物。4. 二氧化碳在室温下很容易用钳形膦镍化合物、钳形膦钯化合物、钳形二甲基氨基甲基锡化合物和三(2-吡啶硫基)甲烷锌化合物等固定剂固定。
