Abstract
The development of a highly active and selective porphyrin-based epoxide carbonylation catalyst,[(OEP) Cr (THF) 2][Co (CO) 4](1; OEP= octaethylporphyrinato; THF= tetrahydrofuran), is detailed. Complex 1 is a separated ion pair composed of a tetracarbonylcobaltate anion and an octahedral chromium porphyrin complex axially ligated by two THF ligands. Regarding the carbonylation of epoxides to β-lactones, catalyst 1 ...
