• ligands
  • Fullerene ligands also bind with palladium in similar ways as ethylene. (wikipedia.org)
  • Complex B reacts in a transmetallation with the copper acetylide, complex F, which is produced in the copper cycle, to give complex C, expelling the copper halide, complex G. Both organic ligands are trans oriented and convert to cis in a trans-cis isomerization to produce complex D. In the final step, complex D undergoes reductive elimination to produce the alkyne, with regeneration of the palladium catalyst. (wikipedia.org)
  • isotopes
  • clarification needed] Palladium films with defects produced by alpha particle bombardment at low temperature exhibit superconductivity having Tc=3.2 K. Naturally occurring palladium is composed of seven isotopes, six of which are stable. (wikipedia.org)
  • carbon
  • More than half the supply of palladium and its congener platinum is used in catalytic converters , which convert as much as 90% of the harmful gases in automobile exhaust ( hydrocarbons , carbon monoxide , and nitrogen dioxide ) into less noxious substances ( nitrogen , carbon dioxide and water vapor ). (wikipedia.org)
  • This process involves the formation of a palladium-carbon covalent bond. (wikipedia.org)
  • Palladium is also prominent in carbon-carbon coupling reactions, as demonstrated in tandem reactions. (wikipedia.org)
  • Filamentous carbon can also form when acetylene decomposes on films of palladium and silicon dioxide. (wikipedia.org)
  • However, filamentous carbon does not form on the palladium and silicon dioxide films if they are preheated with hydrogen at temperatures of 597 °C (1,107 °F). This is because in those conditions, the palladium and silicon dioxide react to form palladium silicide. (wikipedia.org)
  • Ammonium formate can also be used in palladium on carbon (Pd/C) reduction of functional groups. (wikipedia.org)
  • platinum
  • Palladium is a soft silver-white metal that resembles platinum. (wikipedia.org)
  • Others, like palladium, platinum and gold, do not react with the atmosphere at all. (wikipedia.org)
  • As a result, since no gelatin emulsion is used, the final platinum image is absolutely matte with a deposit of platinum (and/or palladium, its sister element which is also used in most platinum photographs) absorbed slightly into the paper. (wikipedia.org)
  • Many[quantify] practitioners have abandoned platinum and only use palladium[citation needed]. (wikipedia.org)
  • He also developed the palladium process requiring palladiotype paper and a silver-platinum paper, satista. (wikipedia.org)
  • wherein
  • 8. The leadframe according to claim 1 wherein said palladium layer has a thickness in the range from about 20 to 60 nm. (google.com)
  • B44d 1/44 ABSTRACT OF THE DISCLOSURE A method for forming a non-porous hydro gen-permeable palladium alloy film on a porous ceramic support wherein a film of palladium dispersed in a vitreous glaze is first deposited on the support, and a thin film of an alloying metal is deposited on the palladium film and heated to effect interdilfusion of the alloying metal with the palladium.

  • iodine
  • This complex reacts with electrophilic iodine to N,N-dimethyl-3-iodoaniline: Directed ortho metalation. (wikipedia.org)
  • porous
  • Some of the most advanced membranes were produced by retired WPI chemical engineering professor Yi Hua "Ed" Ma, who, with considerable funding from industry and the U.S. Department of Energy, pioneered a process for binding palladium to a porous steel tube, resulting in palladium layers as thin as 5 to 10 microns. (eurekalert.org)
  • metal
  • It reacts with many metal chlorides to form tetrachloroiodides, and hydrolyses in water. (wikipedia.org)
  • Most of the hydrogen separation membranes currently being developed use the precious metal palladium, which has unusually high hydrogen solubility and permeance (which means that hydrogen easily dissolves in and travels through the metal, while other gases are excluded). (eurekalert.org)
  • In addition, a membrane made with a film of liquid metal should not be prone to the defects and cracks that can render a palladium membrane unusable. (eurekalert.org)
  • The WPI study, published in the Journal of the American Institute of Chemical Engineers , is the first to demonstrate that in addition to these advantages, liquid-metal membranes also appear to be significantly more effective than palladium at separating pure hydrogen from other gases, suggesting that they may provide a practical and effective solution to the challenge of supplying affordable hydrogen for fuel-cell vehicles. (eurekalert.org)
  • This hydrogen gas is adsorbed onto the surface of the palladium metal, where it can react with various functional groups. (wikipedia.org)
  • potassium
  • The process using palladium alone (sodium tetrachloropalladate) is similar to standard processes, but rather than using ferric oxalate plus potassium chlorate as the restrainer (which is ineffective for palladium), a weak solution of sodium chloroplatinate is used instead. (wikipedia.org)
  • give
  • Ketenes also add NOCl, giving nitrosyl derivatives: H2C=C=O + NOCl → ONCH2C(O)Cl Propylene oxide reacts with NOCl to give an α-chloronitritoakyl derivative: It converts amides to N-nitroso derivatives. (wikipedia.org)
  • Hydrocarbon A also reacts with 0504 to give diol B. When oxidized with KM [104 in acidic solution, A gives two fragments. (coursehero.com)
