Abstract: High Resolution Image Download MS PowerPoint Slide Alkene isomerization holds significant importance in organic chemistry and various chemical industries; however, achieving a high selectivity remains a major challenge. This comprehensive computational investigation delves into the mechanistic parameters governing alkene isomerization catalyzed by a modular Ni(0)/silane system. By systematically analyzing electronic and steric influences of both the substrate and catalyst, the study unveils critical insights into factors that modulate catalytic selectivity and productivity of the isomerized products. In particular, the [3,1]-hydrogen migration pathway in olefins is studied, with a focus on E / Z stereoselectivity. Overall, our findings elucidate the subtle interplay between catalyst design and substrate structure, offering potential design principles for the development of more efficient nickel-catalyzed alkene isomerization processes within synthetic and industrial contexts.
