Factors Affecting the Mechanism of 1,3-Butadiene Polymerization at Open Metal Sites in Co-MFU-4l

Abstract: Selective polymerization of 1,3-butadiene to form 1,4-cis-polybutadiene (PBD) is a fundamental challenge in the modern rubber industry. However, current industrial heterogeneous catalysts cannot offer extremely high (>99%) 1,4-cis selectivity. Recently, the Dincă group reported a highly stereoselective polymerization of 1,3-butadiene using a transition-metal loaded metal-organic framework (MOF) catalyst Co­(II)-MFU-4l (J. Am. Chem. Soc.20171391266412669). We here undertake a computational investigation on the… Show more

“…One possibility to assess the accuracy of the DF would be to perform post-HF calculations, such as DLPNO–CCSD­(T), but our system is relatively large in terms of the number of atoms and the number of species involved in the mechanism. Indeed, only a few studies report the use of this method on selected MOF cluster structures. , There is a recent study on transition metal barrier heights at DLPNO–CCSD­(T) and DFT levels, but no reactions involving Zr were included in the database.…”

“…33 Solvation effects ( G sol ) were considered in single-point energy calculations using the SMD model (toluene as the solvent). 41 The contribution ( G std ) originating from the change of the standard state from the gas phase to solvent environment (1 mol L −1 ) was also included. 42 As such, the relative Gibbs free energy (Δ G ) is given by Δ G = Δ E + Δ G therm + Δ G sol + Δ G std .…”
