Abstract

The redox properties of ethyl diethoxyphosphoryldithioacetate (1), methyl diethoxyphosphorylfluorodithioacetate (2) and methyl diethoxyphosphoryldifluorodithioacetate (3) were measured by cyclic voltammetry. Addition of free radicals to the three dithioesters led to the detection of the ESR spectra of the spin adducts only with the last two compounds. Based on the reduction potentials of the three dithioacetates, this may be explained by capto-dative stabilization of the adducts. On the basis of DFT calculations, the temperature dependent variations of the spectral patterns exhibited by the radicals were attributed to restricted rotation about the Cα–SMe bond.

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.
