Abstract

The ion pair [N(n-butyl)4]+[B(n-butyl)4]- in CCl4 shows a BR4- → NR4+ outer-sphere charge transfer (OSCT) absorption at λ = 306 nm (sh, ε = 420 dm3 M-1 cm-1). OSCT excitation of the ion pair in CH2Cl2irr > 275 nm) leads to a photo­ lysis with ∅ = 1.5 x 10-3 at λirr = 280 nm. Octane is formed as photoproduct.
