Phosphanyl-substituted siloles: synthesis, optical and electrochemical studies and computations
Résumé
In this paper, we report the synthesis and characterization of a series of phosphanyl-substituted siloles. The chemical modification (oxidation, sulfurization, alkylation and complexation) results in a change in the energy levels of frontier orbitals, which has further been studied by UV-Vis absorption spectroscopy and electrochemistry. Significantly, despite their high "s" 2 character the phosphorus lone pairs of the 2,5-bisphosphanylsilole can combine with the π-system of the silole core resulting in a somewhat destabilized HOMO. The structural aspects of these new siloles have been investigated employing single-crystal X-ray diffraction and DFT calculations.
