Unsaturated carboxylic acids from CO2
In the previous years it was shown that the chemical use of CO2 cannot compensate the rising CO2 emissions and solve a potential anthropogenic global warming effect. However, CO2 is a valuable C1-building block and can be used like CO to introduce important functionalities in organic molecules. But the use is limited by the high thermodynamic stability of CO2 compared to other reagents. This is reflected by the limited application of CO2 today. A challenge for the chemists is to identify molecules which react efficiently with CO2 but also provide molecules of commercial interest. Special (organometallic) catalysts can provide a powerful aid to convert CO2 into new molecules.
Besides (in)organic or polymeric carbonates, the synthesis of carboxylic acids is an attractive field for the use of CO2. Especially unsaturated carboxylic acids are a key building block in the chemical industry. They are used in a large variety of final products like paints, polymeric glazing and super-absorbing polymers. Within the presentation, a new pathway towards such acids will be provided and discussed.
