Oxidative addition of halogens to a Dineophylplatinum(II) Complex: Halogen complexes and fluxional Platinum(IV) complexes

High Selectivity in Csp2–Csp2 versus Csp3–O Reductive Elimination from Cycloplatinated(IV) Complexes

“…However, after conversion to 3a , the analogue proton shifted to 9.64 ppm with 3 J PtH 2 = 37.1 Hz. This increase in the coupling constant is consistent with the conversion of Pt­(IV) to Pt­(II). − Our signal assignments of H 2 can be verified by the 1 H­{ 195 Pt}­NMR spectrum of 3a , which does not show Pt satellites (Figure S21). It is worth noting that the 3 J PtH 2 values are comparable to those reported for the same H atoms in other κ 1 N-HC ∧ N platinum­(II) complexes. ,, …”
