We report synthetic strategies for installing platinum group metals (PGMs: Pd, Rh, Ir, and Pt) on a scorpionate-derived linker (TpmC*) within a metal-organic framework (MOF), both by room-temperature postsynthetic metalation and by direct solvothermal synthesis, with a wide range of metal loadings relevant for fundamental studies and catalysis. In-depth studies for the palladium adduct Pd(II)@Zr-TpmC? by density-functional-theory-assisted extended X-ray absorption fine structure spectroscopy reveals that the rigid MOF lattice enforces a close Pd(II)-Napical interaction between the bidentate palladium complex and the third uncoordinated pyrazole arm of the TpmC? ligand (Pd-Napical = 2.501 ± 0.067 ?), an interaction that is wholly avoided in molecular palladium scorpionates.
Pt(II) and Pd(II)-assisted coupling of nitriles and 1,3-diiminoisoindoline: Synthesis and luminescence properties of (1,3,5,7,9-pentaazanona-1,3,6,8-tetraenato)Pt(II) and Pd(II) complexes

Treatment of trans-[PtCl2(NCR)2] 1 (R?=?Me (1a), Et (1b), o-ClC6H4 (1c), p-ClC6H4 (1d), p-(HC[dbnd]O)C6H4 (1e), p-O2NC6H4CH2 (1f)) with 1,3-diiminoisoindoline HN[dbnd]CC6H4C(NH)[dbnd]NH 2 gives access to the corresponding (1,3,5,7,9-pentaazanona-1,3,6,8-tetraenato)Pt(II) complexes [PtCl{NH[dbnd]C(R)N[dbnd]C(C6H4)NC[dbnd]NC(R)[dbnd]NH}] 3a–f, in good yields (65–70%). The reaction of trans-[PdCl2(NCMe)2] 4a with 2 furnishes (1,3,5,7,9-pentaazanona-1,3,6,8-tetraenato)Pd(II) complex [PdCl{NH[dbnd]C(Me)N[dbnd]C(C6H4)NC[dbnd]NC(Me)[dbnd]NH}] 5a, in good yield (65%). However, the reaction of trans-[PdCl2(NCR)2] 4 (R?=?Ph (4b), p-MeC6H4CH2 (4c), p-(HC[dbnd]O)C6H4 (4d), p-O2NC6H4CH2 (4e)) with 2 gives a number of unidentified products. The compounds 3a–f and 5a were characterized by IR,1H,13C and DEPT-135 NMR spectroscopies, elemental analyses and, in the case of the Pt(II) complex [PtCl{NH[dbnd]C(Me)N[dbnd]C(C6H4)NC[dbnd]NC(Me)[dbnd]NH}] 3a, also by X-ray diffraction analysis. Compounds 3a and 3b were also characterized by UV–Vis absorption and luminescence emission spectroscopies. Emission quantum yields of ca. 3?×?10?3 were obtained in dichloromethane solution, and luminescence lifetimes are in the order of the tens of nanoseconds. Both compounds also exhibited luminescence in solid state (polystyrene matrix), with luminescence lifetimes in the order of hundreds of nanoseconds.

Paragraph 0217-0218, (2018/10/19)
PROBLEM TO BE SOLVED: To provide methods of producing a perfluoroalkylphosphine compound improved in a phosphorus element yield and a chemical yield. SOLUTION: A method of producing a perfluoroalkylphosphine compound comprises either reacting a perfluoroalkyl iodide with, e.g., 2,4,6-trimethylbenzoyldiphenylphosphine oxide (TMDPO) or a triarylphosphine such as triphenylphosphine, which are easily available, in the presence of a radical generator such as azobis(isobutyronitrile) or light irradiation, or reacting TMDPO or the like with perfluoroalkyl iodide in the presence of diphenylphosphine, diethylphosphine, dicyclohexylphosphine or the like.
