Catalytic Organic Reactions in Water toward Sustainable Society

Traditional organic synthesis relies heavily on organic solvents for a multitude of tasks, including dissolving the components and facilitating chemical reactions, because many reagents and reactive species are incompatible or immiscible with water. Given that they are used in vast quantities as compared to reactants, solvents have been the focus of environmental concerns. Along with reducing the environmental impact of organic synthesis, the use of water as a reaction medium also benefits chemical processes by simplifying operations, allowing mild reaction conditions, and sometimes delivering unforeseen reactivities and selectivities. After the “watershed” in organic synthesis revealed the importance of water, the development of water-compatible catalysts has flourished, triggering a quantum leap in water-centered organic synthesis. Given that organic compounds are typically practically insoluble in water, simple extractive workup can readily separate a water-soluble homogeneous catalyst as an aqueous solution from a product that is soluble in organic solvents. In contrast, the use of heterogeneous catalysts facilitates catalyst recycling by allowing simple centrifugation and filtration methods to be used. This Review addresses advances over the past decade in catalytic reactions using water as a reaction medium.

Sustaining the Transition from a Petrobased to a Biobased Chemical Industry with Flow Chemistry

In the current context of transitioning to more sustainable chemical processes, the upgrading of biobased platform molecules (i.e., the chemical transformation of widely available low molecular weight entities from biomass) is attracting significant attention, in particular when combined with enabling continuous flow conditions. The success of this combination is largely due to the ability to explore new process conditions and the perspective of facilitating seamless scalability while maintaining a small overall footprint. This review considers representative continuous flow processes which utilize a selection of currently popular platform molecules that target industrially relevant building blocks, including (a) commodity chemicals, (b) specialty and fine chemicals, and (c) fuels and fuel additives.
