Oxidative Addition of a CH Bond at a Two‐coordinated Phosphenium Cation Reaction of ArP(Cl)SAr ( 1 ) [Ar = 2,4,6‐( t ‐Bu) 3 C 6 H 2 ] with AgSbF 6 in ether at 0°C affords the compound . This exists in two different forms 2a and 2b . Form 2a is a phosphonium cation. In the IR and 31 P{ 1 H} NMR spectra of 2b an interaction between the and SbF 6 − units is observed. 2a and 2b are in an equilibrium which depends on the temperature. 2 is formed via the unstable (arylthio)‐phosphenium cation with a σ 2 ,λ 3 ‐phosphorus.
