β-Diiminato ligand (L) transformations in reactions of KL with PI3 and I2 [L = {N(C6H3Pri2-2,6)C(H)}2CPh]

Abstract

The reaction of the potassium β-diiminate KL (L = [{N(Ar)C(H)}₂CPh]⁻; Ar = C₆H₃Prⁱ₂-2,6) with PI₃ unexpectedly produced a phosphenium salt of the intermolecularly C,C-coupled ligand [P(I){N(Ar)CH}₂C(C₆H₄-4)C(Ph)(CHNAr)₂]⁺[I₃]⁻, while an intramolecularly N,N-coupled salt [N(Ar)C(H)C(Ph)C(H)N(Ar)]⁺[I₅]⁻ was isolated from KL + I₂.
