  of fluorination reaction of bisaryl-platinum(II) complexes, each possible competitive pathway of Ar–Ar and Ar–F formation can be selectively controlled. It was discovered that steric hindrance, type of fluorinating reagent, and temperature of reaction are determinants for Ar–F vs Ar–Ar bond formation pathway from bisaryl-fluoro-platinum(IV) complexes. The combination of bulky ligands such as mesityl

  biaryl product was formed with >90% yield within <30 minutes at RT. Moreover, by experimental and computational studies, the influence of ancillary ligands on the Ar–Ar reductive elimination reaction was investigated by changing their steric and electronic effects. The stability of some platinum fluoride complexes in the presence of water was also investigated.

  A study of the basis of selectivity of C-H bond activation of anisole by electrophilic methylplatinum(II) complexes is reported. Anisole reacts with [PtXMe(NN)] in trifluoroethanol solvent to give methane and [PtXAr(NN)], Ar = 2-, 3-, and 4-anisyl, in 90:8:2 ratio when X = HOB(C6F5)(3) and NN = (2-C5H4N)(2)CO (DPK) but not when NN = 2,2'-bipyridine. Similar results are obtained when X = triflate or when NN = (2-C5H4N)(2)NH. Competition between reaction of anisole and anisole-d(8) with [PtXMe(NN)], X = HOB(C6F5)(3) and NN = DPK, in trifluoroethanol gave an isotope effect k(H)/k(D) = 3.6. Several 4-anisyl complexes, [PtClAr(NN)], [PtAr2(NN)], and [PtMeAr(NN)], NN = DPK, DPA, or bipy, were prepared and reacted with HX [X = Cl, OTf, or HOB(C6F5)(3)]. Reaction of [PtMeAr(NN)], NN = DPK or bipy, with HX gave a detectable hydride [PtXHMeAr(NN)] when X = Cl, followed by loss of methane to give [PtClAr(NN)], but only [Pt(OTf)Ar(NN)] was detected when X = OTf. Reaction with more HOTf gave anisole and [PtX2(NN)], X = OTf, and no isomerization of the 4-anisyl group to the more favored 2-anisyl group was observed at any stage. The similar reaction of [PtMeAr(NN)] and HOTf in CD3OD/CD2Cl2 gave CHnD4-n (n = 0-4) and mostly 4-MeOC6H4D. It is argued that the anisole C-H bond cleavage step in anisole activation, or the anisyl-H bond forming step in protonolysis, is responsible for the observed selectivity in these reactions.
