Metal-Organic Frameworks for CO2 Chemical Transformations.
Carbon dioxide (CO2 ), as the primary greenhouse gas in the atmosphere, triggers a series of environmental and energy related problems in the world. Therefore, there is an urgent need to develop multiple methods to capture and convert CO2 into useful chemical products, which can significantly improve the environment and promote sustainable development. Over the past several decades, metal-organ...
متن کاملWater-accelerated organic transformations
Rather than quenching all reactive intermediates and arresting the reaction, the addition of catalytic or stoichiometric (1–10 equiv.) quantities of H2O to organic and organometallic processes can lead to surprisingly beneficial effects on reaction rate, product yield, and regio-, diastereoand enantioselectivity. A most intriguing aspect of H2O-promoted transformations is the role that this str...

متن کاملOrganic synthetic transformations using organic dyes as photoredox catalysts.
The oxidizing ability of organic dyes is enhanced significantly by photoexcitation. Radical cations of weak electron donors can be produced by electron transfer from the donors to the excited states of organic dyes. The radical cations thus produced undergo bond formation reactions with various nucleophiles. For example, the direct oxygenation of benzene to phenol was made possible under visibl...
