containing compounds through a number of methods; however, direct introduction of N- and O-functionality remains challenging. Presented herein is a general method to allow for the simultaneous installation of N- and O-functionality to construct unexplored N–O heterocyclic and amino-alcohol scaffolds. This transformation uses earth abundant copper salts to facilitate the formation of a carbon-centered radical
A resin composition is provided containing a resin (preferably a thermoplastic resin) and an isoxazolidine. The composition exhibits enhanced melt stability and colour stability. The composition is useful for making thermoplastic articles such as extruded sheet and film. Preferably the thermoplastic resin is a polyolefin such as polypropylene. A method for stabilizing thermoplastic polymers is also provided.
