M. Z. Slawin, Jens Beckmann, J. Derek WoollinsA series
of peri-substituted phosphorus–tellurium
systems R′Te–Acenap–PR2 (R′
= Ph, p-An, Nap, Mes, Tip; Acenap = acenaphthene-5,6-diyl
(–C12H8); R = iPr, Ph) exhibiting large “through-space” spin–spin
coupling constants and the “onset” of three-center four-electron
type interactions is presented. The influence of the substituents
at the phosphorus and tellurium atoms as well as their behavior upon
oxidation (with S, Se) or metal-coordination (Pt, Au) is discussed
using NMR spectroscopy, single-crystal X-ray diffraction, and advanced
density functional theory studies including NBO, AIM, and ELI-D analyses.
