Abstract
The utilization of renewable platform molecules as feedstocks for manufacturing high-value-added fine chemicals and liquid fuels has become crucial for green and sustainable chemistry and represents a rewarding challenge for today's society. Photochemistry and electrochemistry are effective and powerful tools for the transformation of biomass molecules through free radical intermediates under mild reaction conditions. Numerous direct decarboxylative reactions, without the need for prefunctionalization of carboxylic acids, by photocatalysis or electrocatalysis have been developed during the last few years, with more efficient, step-economical, and low energy consumption processes. In this review, we summarize recent advances in photochemical and electrochemical decarboxylative reactions for the synthesis of alkane fuels and high-value chemicals by utilizing biomass-derived free carboxylic acids as a sustainable source. These transformations can be categorized into four main types as follows: (1) decarboxylative reduction, (2) decarboxylative elimination, (3) decarboxylative coupling, and (4) decarboxylative oxidation. The scope and limitations of these conversions and mechanisms are discussed in detail. Finally, the challenges and perspectives for light or electrically driven decarboxylative transformation of renewable carboxylic acid feedstocks are proposed.
期刊介绍:
Green Chemistry is a journal that provides a unique forum for the publication of innovative research on the development of alternative green and sustainable technologies. The scope of Green Chemistry is based on the definition proposed by Anastas and Warner (Green Chemistry: Theory and Practice, P T Anastas and J C Warner, Oxford University Press, Oxford, 1998), which defines green chemistry as the utilisation of a set of principles that reduces or eliminates the use or generation of hazardous substances in the design, manufacture and application of chemical products. Green Chemistry aims to reduce the environmental impact of the chemical enterprise by developing a technology base that is inherently non-toxic to living things and the environment. The journal welcomes submissions on all aspects of research relating to this endeavor and publishes original and significant cutting-edge research that is likely to be of wide general appeal. For a work to be published, it must present a significant advance in green chemistry, including a comparison with existing methods and a demonstration of advantages over those methods.
