DOI: 10.1021/acs.macromol.6b02398
Abstract: The strong Lewis acid Al(C6F5)3, in combination with a strong Lewis base N-heterocyclic olefin (NHO), cooperatively promotes the living ring-opening (co)polymerization of lactones, represented by δ-valerolactone (δ-VL) and e-caprolactone (e-CL) in this study. Medium to… read more here.

DOI: 10.1039/d1sc02819g
Abstract: A mesoionic N-heterocyclic olefin (mNHO) was introduced as a metal-free catalyst for the reductive functionalization of CO2 leading to consecutive double N-methylation of primary amines in the presence of 9-borabicyclo[3.3.1]nonane (9-BBN). A wide range of… read more here.
