Abstract

The gold(I)-catalysed divinylcyclopropane–cycloheptadiene rearrangement has been studied computationally within the Density Functional Theory framework. Regardless of the ligand directly attached to the transition metal (L = phosphine, phosphite and N-heterocyclic carbene), the process is found to occur concertedly via endo-boatlike transition structures. The influence of the transition metal fragment on the transformation is analysed and compared to the corresponding uncatalysed process in terms of the computed activation barriers, synchronicity and aromaticity of the associated transition states.

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
