In this hot paper, published in Catalysis Science &Technology, Kleij et al. describe how Alkylated Zn(salpyr) complexes (salpyr = N,N?-bis[salicylidene]-3,4-pyridinediamine) were prepared and used as catalyst precursors for the formation of cyclic carbonates from a range of (functional) epoxides and CO2. Reaction conditions were optimized to achieve good isolated yields of the targeted products. The molecular structure of the most active bifunctional Zn(salpyr) derivative was also resolved by X-ray diffraction.
The paper is free to access until 4th April.
