The syntheses of the molecules Ni(PMe3)4 and Pt(PMe3)4 are reported for the first time.The platinum compound is much less stable than the nickel analogue.Raman and i.r. spectra have been obtained for the nickel compound and a complete vibrational assignment is proposed on the basis of Td molecular symmetry.For the platinum compound only the i.r. spectrum has been obtained.
Method for preparing palladium (0) or platinum (0) composite compound from triphenylphosphine

Paragraph 0033; 0034, (2019/01/08)
The invention provides a method for preparing a palladium (0) or platinum (0) composite compound from triphenylphosphine; with use of palladium chloride (PdCl2) or hydrochloroplatinic acid (H2PtCl6.xH2O) as a starting material, preliminary preparation reaction is not needed, and commercially purchased palladium chloride or hydrochloroplatinic acid can be directly used for reaction. The reaction process is simple, all the reactions are carried out in a same reactor, separation of intermediate products is not needed, and the loss is reduced; the yield of target products is high; the recovery problem of reaction residues is simplified. The product has high reactivity and catalytic activity in various reactions, and has broad application prospects.

Several tricyclic phenoxasilin and phenazasiline heterocycles were synthesized from the corresponding 2,2′-dilithio-diphenyl ether or diphenyl amine precursor and silicon tetrachloride (or trichlorosilane) followed by reduction with lithium aluminum hydride [H2SiAr2: Ar2 = C12H8O (1); Ar2 = C 14H12O (2); Ar2 = C13H11N (3); Ar2 = C15H15N (4); Ar2 = C13H9Br2N (5)]. The reactivity of hydrosilanes 1-5 with (Ph3P)2Pt(η2-C2H 4) (6) was investigated. At room temperature, mononuclear complexes, (Ph3P)2Pt(H)-(SiAr2H) and (Ph 3P)2Pt(SiAr2H)2, were generally observed by NMR spectroscopy but were too reactive or unstable to isolate. Dinuclear and in some cases trinuclear Pt-Si-containing complexes were observed as the major products from the reactions. Symmetrical dinuclear complexes, [(Ph3P)Pt(μ-η2-H-SiAr2)]2 (8 and 22, respectively), were produced from the reaction of 1 or 3 with 6. In contrast, reaction of silane 2 with 6 produced a trinuclear complex, [(Ph 3P)Pt(μ-SiAr2)]3 (16), as the major product. However, reaction of 4 or 5 with complex 6 produced an unsymmetrical dinuclear complex, [(Ph3P)2Pt(H)(μ-SiAr2)(μ- η2-H-SiAr2)Pt(PPh3)] (26 and 30, respectively), as the major component. The molecular structures of a symmetrical (22) and unsymmetrical dinuclear (30) complex as well as a trinuclear (16) complex were determined by X-ray crystallography.
