Difficulties in product separation and ineffective recycling of the homogenous catalyst deter the mass production of beta-lactones via carbonylation of epoxides. Herein, we address these issues, for the first time, using a recyclable heterogenized catalyst [bpy-CTF-Al(OTf)(2)][Co(CO)(4)] that efficiently converts propylene oxide (PO) to beta-butyrolactone with high selectivity.
