Abstract
Disclosed herein are compounds and methods useful as carbonylation catalysts that improve steric properties so that reaction with epoxide is improved, reaction with lactones is avoided, and polymer bonds to the metal centers are weakened, which facilitates faster ring closure, that improve stability of the carbonylation catalyst by not being susceptible to hydrolysis, which reduces side products and improves recovery yields of the carbonylation catalyst after using to make lactones, and that have improved steric and electron properties so that release time of a lactone product is minimized, which reduces side reactions.
