Sustainable Chemistry

The presidents of the chemical societies of France (SFC), Germany (GDCh), Japan (CSJ), the Netherlands (KNCV), the UK (RSC), and the USA (ACS) recently pledged on behalf of about 300,000 members to "work together to promote global sustainable development, demand responsible use of resources, and ensure that the next generation of scientists protects and maintains the well-being of Earth and its inhabitants." They deem this issue an urgent one, and that chemistry is absolutely essential to the development of solutions.

Catalytic Cracking of Lactide and Poly(Lactic Acid) to Acrylic Acid at Low Temperatures

Catalytic Cracking of Lactide and Poly(Lactic Acid) to Acrylic Acid at Low Temperatures

Sweet diapers! A radical new and efficient synthetic method is presented, which converts lactide to acrylic acid in a convenient one-pot/one-step process. Acrylic acid is a highly valued chemical and a starting material for superabsorbent polymers (SAPs), which finds their prime application in diapers. The technique presented here is an important step towards full biobased SAPs and turns lactide into a key platform chemical in the biobased arena.

Elemental Sulfur and Molecular Iodine as Efficient Tools for Carbon-Nitrogen Bond Formation through Redox Reactions

Elemental Sulfur and Molecular Iodine as Efficient Tools for Carbon‐Nitrogen Bond Formation through Redox Reactions

An elemental match! Carbon–nitrogen bonds are ubiquitous in organic chemistry. This review presents some recent advances in redox reactions that use elemental sulfur and molecular iodine as excellent reagents/catalysts to provide these important linkages.

Decarboxylative Giese-Type Reaction of Carboxylic Acids Promoted by Visible Light: A Sustainable and Photoredox-Neutral Protocol

Decarboxylative Giese‐Type Reaction of Carboxylic Acids Promoted by Visible Light: A Sustainable and Photoredox‐Neutral Protocol

The decarboxylative alkylation of carboxylic acids can be efficiently promoted by visible light under air at room temperature by using 9-mesitylene-10-methylacridinium perchlorate ([Acr-Mes]ClO4) as photocatalyst. A range of readily available starting materials are well tolerated in this transition-metal-free protocol.
