摘要: Even though carbon dioxide is used in a great number of industrial applications, it remains molecule with low reactivity. Its activation by coordination to metal complexes both stoichiometric and catalytic reactions. This article describes the different kinds observed gas phase, cryogenic solids, solution, briefly presents reactivity coordinated CO2 toward electrophiles nucleophiles. Keywords: carbon dioxide; transition-metal complexes; activation small molecules; coordination chemistry; organometallic chemistry
