  Acceptor Pincer Coordination Chemistry of Platinum: Reactivity Properties of (^CF₃PCP)Pt(L)⁺ (L = NC₅F₅, C₂H₄)

  摘要：

  Synthetic strategies toward the synthesis of electron-poor pincer complexes ((PCP)-P-CF3)PtH and ((PCP)-P-CF3)Pt(eta(2)-H-2)(+) are described. Metathesis of ((PCP)-P-CF3)PtCl with hydride reagents does not lead to ((PCP)-P-CF3)PtH; ((PCP)-P-CF3)PtCl with KH in tetrahydrofuran (THF) afforded an unusual metallated bimetallic pincer product ((PCP)-P-CF3)Pt[kappa(1)-C,kappa P3-,C,P-2,6-(CHP(CF3)(2))(CH2P(CF3)(2))-C6H3]PtCl, which has been structurally characterized. Chloride abstraction from ((PCP)-P-CF3)PtCl or protonolysis of ((PCP)-P-CF3)PtMe in the presence of H-2 gives the structurally characterized hydride-bridged dimer {((PCP)-P-CF3)Pt}(2)(mu-H)(+). In the presence of trapping ligands H2O, C2H4, or pentafluoropyridine, the corresponding complexes ((PCP)-P-CF3)Pt(L)(+) (L = H2O, C2H4, NC5F5) are cleanly produced and have been structurally characterized. The C2H4 and NC5F5 adducts may be alternatively prepared by methide abstraction from (CF3PCP)PtMe with Ph3C+B(C6F5)(4)(-) in the presence of trapping ligand. Evidence for the transient formation of ((PCP)-P-CF3)PtH from treatment of ((PCP)-P-CF3)PtCl or ((PCP)-P-CF3)Pt(NC5F5)(+) with Et3Si+B(C6F5)(4)(-) is presented. ((PCP)-P-CF3)Pt(C2H4)(+) serves as a catalyst for ethylene hydrogenation (0.30 turnovers h(-1), 70 degrees C) and hydrosilation with Et3SiH (460 turnovers h(-1), RT) and Cl3SiH (5 turnovers h(-1), RT). At elevated temperatures, ((PCP)-P-CF3)Pt(C2H4)(+) also exhibits limited ethylene dimerization activity (0.07 turnovers h(-1), 155 degrees C and 1-butene isomerization (0.9 turnovers h(-1), 80 degrees C).

  摘要：

  报道了全氟烷基取代的“夹子”型PCP配体1,3-C6H4（CH2P（Rf）2）2（Rf = CF3，C2F5）和铂配位研究（Rf = CF3）的合成。1,3-C6H4（CH2P（CF3）2）2（CF3PCPH）在环境温度下与（cod）Pt（Me）Cl（cod = 1,5-环辛二烯）和（cod）PtMe2反应以提供未金属化的PCPH桥连产物[（CF3PCPH）Pt（Me）Cl] x和顺式-[（CF3PCPH）PtMe2] 2。顺式[[（CF3PCPH）PtMe2] 2是可溶的，并已在光谱和晶体学上进行了表征。这些化合物的热解导致甲烷的损失以及金属化配合物（CF3PCP）PtCl和（CF3PCP）PtMe的形成。用MeMgBr处理（CF3PCP）PtCl为（CF3PCP）PtMe提供了另一种途径。
