A family of cis-macrocyclic diphosphines: modular, stereoselective synthesis and application in catalytic CO2/ethylene coupling

The stereoselective synthesis of a family of cis-macrocyclic diphosphines was achieved in only three steps from white phosphorus and commercial materials. These new ligands showed activity in the nickel-catalyzed coupling of CO2 and ethylene.

A quantitative definition of hypervalency

The concept of hypervalency has had a long but troubled history. Although several attempts have been made to dispense with the concept altogether, it remains in widespread use. By developing a simple but quantitative measure of hypervalency, the concept can be rehabilitated to provide valuable chemical insights in the context of Lewis models.

About this collection

We are delighted to present this web collection which contains selected contributions from the ISACS19: Challenges in Chemical Renewable Energy meeting held in Rio de Janeiro, Brazil in September 2015. Delegates from countries around the world gathered to hear from leading researchers in this exciting field and now we have the opportunity to share with you exciting new research from a number of our plenary speakers and scientific committee members. We hope you enjoy the collection.
