What is Tetrakis(triphenylphosphine)palladium(0) used for?

Tetrakis(triphenylphosphine)palladium(0) is the chemical compound Pd[P(C6H5)3]4, often abbreviated Pd(PPh3)4, or even PdP4. It is a bright yellow crystalline solid that becomes brown upon decomposition in air.
Preparation
Tetrakis(triphenylphosphine)palladium(0) was first prepared by Lamberto Malatesta and his group in Milan in the 1960s by reduction of sodium chloropalladate with hydrazine in the presence of the phosphine. It is commercially available, but can be prepared in two steps from Pd(II) precursors.
Applications of Tetrakis(triphenylphosphine)palladium(0)
Pd(PPh3)4 is widely used as a catalyst for palladium-catalyzed coupling reactions. Prominent applications include the Heck reaction, Suzuki coupling, Stille coupling, Sonogashira coupling, and Negishi coupling. These processes begin with two successive ligand dissociations followed by the oxidative addition of an aryl halide to the Pd(0) center:Pd(PPh3)4 + ArBr → PdBr(Ar)(PPh3)2 + 2 PPh3

What is Cholesteryl butyrate (Cholesterol butyrate)?

Cholesteryl butyrate (Cholesterol butyrate)
SYNONYMS Cholesteryl butanoate
Molecularformula:C31H52O2
Cas No.:521-13-1
Molecularweight:456.8
Appearance: WHITE POWDER
Melting point: 98-100 °C REM. ON CHROMATOGRAPHY < 0.1 % CHOLESTEROL
Assay:≥ 99.0 %
Cholesteryl butyrate (Cholesterol butyrate) is a steroid alcohol that is essentially insoluble in aqueous solutions. In mammals, it is normally solubilized by its association with other lipids, such as phospholipids or bile acids thus, most cholesterol is found in cell membranes, plasma lipoproteins, and bile. Cholesterol can be esterified with a fatty acid to form cholesteryl esters. The latter form discrete lipid droplets in cells, especially in cells of steroidogenic tissues, and in the lipid core of low-density lipoproteins in the blood. Cholesterol is a fatty lipid sparingly insoluble in water but soluble in a number of organic solvents.

What is Iridium(III) acetylacetonate?

Iridium(III) acetylacetonates are coordination complexes derived from the acetylacetonate anion and metal ions, usually transition metals. The ligand acetylacetonate is often abbreviated acac. Typically both oxygen atoms bind to the metal to form a six-membered chelate ring. The simplest complexes have the formula M(acac)3 and M(acac)2. Mixed-ligand complexes, e.g. VO(acac)2, are also numerous. Variations of acetylacetonate have also been developed with myriad substituents in place of methyl. Many such complexes are soluble in organic solvents, in contrast to the related metal halides. Because of these properties, acac complexes are sometimes used as catalyst precursors and reagents. Applications include their use as NMR "shift reagents" and as catalysts for organic synthesis, and precursors to industrial hydroformylation catalysts. C5H7O2− in some cases also binds to metals through the central carbon atom; this bonding mode is more common for the third-row transition metals such as platinum(II) and iridium(III).
Iridium(III) acetylacetonate is the formula for two isomers, trans-Ir(acac)2(CH(COMe)2)(H2O) and the more conventional D3-symmetric Ir(acac)3. The C-bonded derivative is a precursor to homogeneous catalysts for C-H activation and related chemistries. Iridium(I) derivatives include square-planar Ir(acac)(CO)2 (C2v-symmetry).
Iridium Acetylacetonate is a Iridium source that is soluble in organic solvents as an organometallic compound (also known as metalorganic, organo-inorganic and metallo-organic Acetylacetonate Packaging, Lab Quantitycompounds). The high purity acetylacetonate anion complexes by bonding each oxygen atom to the metallic cation to form a chelate ring.Because of this property, Iridium Acetylacetonate is commonly used in various catalysts and catalytic reagents for organic synthesis. It is generally immediately available in most volumes.

What is Ruthenium(IV) oxide used for?

Ruthenium(IV) oxide (RuO2) is a black chemical compound containing the rare metal ruthenium and oxygen. The most often used O2 catalyst is ruthenium(IV) oxide; however, care must be taken since hydrates of this oxide exist.
Skeletal formula of ruthenium (IV) oxide
RuO2 is generally used as a catalyst in various industrial applications or an electrode in electrochemical processes. RuO2 is highly reactive with reducing agents, due to its oxidizing properties.
Properties
Ruthenium(IV) oxide takes on the rutile crystal structure, similar to titanium dioxide and several other metal oxides. Due to its structure, ruthenium(IV) oxide easily forms hydrates.
Ruthenium(IV) oxide is a (nearly black) purple crystalline solid at room temperature. The hydrates of RuO2 have a blue color to them.
Ruthenium oxide has great capacity to store charge when used in aqueous solutions. Average capacities of ruthenium(IV) oxide have reached 650 F/g when in H2SO4 solution and annealed at temperatures lower than 200 °C. In attempts to optimise its capacitive properties, prior work has looked at the hydration of ruthenium oxide, its crystallinity and particle size.
Uses
Ruthenium(IV) oxide is extensively used for the coating of titanium anodes for the electrolytic production of chlorine and for the preparation of resistors or integrated circuits.
Ruthenium(IV) oxide is a versatile catalyst and doping agent. Hydrogen sulfide can be split by light by using a photocatalyst of CdS particles doped with ruthenium(IV) oxide loaded with ruthenium dioxide. This may be useful in the removal of H2S from oil refineries and from other industrial processes. The hydrogen produced could be used to synthesize ammonia, methanol, and possibly fuel a future hydrogen economy.
Ruthenium (IV) oxide is being used as the main component in the catalyst of the Deacon process which produces chlorine by the oxidation of hydrogen chloride.It can be also used as active material in supercapacitor because has very high charge transfer capability.
