  CF3CO2H to (dfebp)2Pt generates the expected Pt(II) trans-(dfebp)2Pt(O2CCF3)(H) product, while treatment with the mesitylenium acid (C6Me3H4)+B(C6F5)4− leads to phosphine loss and formation of the arene complex [(η6-C6Me3H3)Pt(dfebp)(H)]+(B(C6F5)4)−. Addition of ethylene to (dfebp)2Pt results in facile and reversible equilibria with the ethylene adducts (dfebp)2Pt(C2H4) and (dfebp)Pt(C2H4)2, which have

• Investigation of Iridium^CF₃PCP Pincer Catalytic Dehydrogenation and Decarbonylation Chemistry

  The iridium fluorinated pincer complex ((PCP)-P-CF3)Ir-(cod) ((PCP)-P-CF3 = 2,6-C6H3(CH2P(CF3)(2))(2)) catalyzes hydrogen transfer from cyclooctane (coa) to tert-butylethylene (tbe) in 1/1 coa/tbe at 200 degrees C to give cyclooctene (coe) and neohexane (tba) at an initial rate of 40 TO h(-1). In 5/1 coa/tbe, higher initial activity (155 TO h(-1)) and higher turnovers (2580 TON's after 1450 min) are found. Samples of 95% the contain significant amounts of isoprene (2-methyl-1,3-butadiene), which reacts with ((PCP)-P-CF3)Ir(cod) to initially form ((PCP)-P-CF3)Ir(isoprene). Alkene inhibition studies show that ((PCP)-P-CF3)Ir is only modestly inhibited (67% reduced initial activity) in the presence of 800 equiv of added coe. Unlike donor pincer systems, no decrease in activity is noted under 1 atm of N-2 or in the presence of excess water. Hydrogenation of ((PCP)-P-CF3)Ir(L) (L = cod, isoprene) did not produce ((PCP)-P-CF3)Ir(H)(x) but instead afforded the first example of the unusual aryl-bridged bimetallic complex [(mu-1 kappa(2)(P,C),2 kappa(2)(P',C)-(PCP)-P-CF3)Ir(H)(2)](2)(mu-(PCPH)-P-CF3)(mu-H), which has been isolated and crystallographically characterized. Ir(I) pincer complexes ((PCP)-P-CF3)Ir(L) (L = MeP(C2F5)(2), CO, dfepe (dfepe = (C2F5)(2)PCH2CH2P(C2F5)(2))) also serve as moderately active aldehyde decarbonylation catalyst precursors for 2-naphthaldehyde with similar activities in diglyme (1.7 TO h(-1), 152 degrees C) and in 1,4-dioxane (0.052 TO h(-1), 94 degrees C). The catalyst resting states are the corresponding five-coordinate carbonyl complexes ((PCP)-P-CF3)Ir(MeP(C2F5)(2))(CO), ((PCP)-P-CF3)Ir(CO)(2), and [((PCP)-P-CF3)Ir-(CO)](2)(mu-dfepe) (CO)](2)(mu-dfepe). DFT studies indicate that the preferred catalyst resting state for alkane dehydrogenation, ((PCP)-P-CF3)Ir-(cod), can be ascribed to the lower steric requirements of the CF3-substituted pincer ligand.

  The comparative reactivity properties of previously reported trans-(dfmp)(2)Pt(Me)X (dfmp = (C2F5)(2)-MeP; X = O2CCF3, OTf, OSO2F) with small molecules are presented. Anionic ligand displacement by CO depends upon X and the corresponding acid solvent. In trifluoroacetic acid, treatment of trans(dfmp)(2)Pt(Me)(O2CCF3) with CO results in loss of dfmp to form the mixed phosphine/carbonyl product (dfmp)(CO)Pt(Me)(O2CCF3). However, in triflic and fluorosulfonic acids trans-(dfmp)(2)Pt(Me)(X) compounds react with CO to form trans-(dfmp)(2)Pt(Me)(CO)(+)(X)(-). trans-(dfmp)(2)Pt(Me)(X) systems react with H-2 under both acidic and aprotic conditions to form trans-(dfmp)(2)Pt(H)(X); trans-(dfmp)(2)Pt(H)(OTf) has been crystallographically characterized. Treatment of trans-(dfmp)(2)Pt(H)(OTf) with CO or dfmp gives trans-(dfmp)(2)Pt(H)(CO)(+) or (dfmp)(3)Pt(H)(+), respectively. In contrast to trans-(dfmp)(2)Pt(Me)(OTf), which releases methane in HOTf, trans-(dfmp)(2)Pt(Me)(OSO2F) in FSO3H at 80 degrees C cleanly produces the reductive elimination product MeOSO2F. Carbonylation of trans-[(dfmp)(2)PtMe(CO)]X-+(-) under 1000 psi CO in turn cleanly produces MeC(O)X at ambient temperatures. The mechanism of reductive elimination from these Pt(II) precursors is discussed.
