Syntheses, structures and theoretical calculations of stable triarylarsine radical cations

Abstract

The first stable triarylarsine radical cation salts 1•+[BArF4] and 2•+[BArF4] were afforded by one-electron oxidation of the triarylarsines Trip3As (1, Trip = 2,4,6-iPr3C6H2) and Dipp3As (2, Dipp = 2,6-iPr2C6H3) with AgSbF6 and NaBArF4 (ArF = 3,5-(CF3)2C6H3), respectively. Their molecular and electronic structures were investigated by single-crystal X-ray diffraction, electron paramagnetic resonance (EPR) and UV-Vis absorption spectroscopy, in conjunction with density functional theory (DFT) calculations. The EPR and computational results demonstrate that the spin density of 1•+ and 2•+ is mainly distributed on the As nuclei.
