Palladium(II) chloride, also known as palladium dichloride and palladous chloride, are the chemical compounds with the formula PdCl 2.PdCl 2 is a common starting material in palladium chemistry – palladium-based catalysts are of particular value in organic synthesis.
Dichlorobis(ethylenediamine)nickel(II) is the inorganic compound with the formula NiCl 2 (en) 2, where en = ethylenediamine. The formula is deceptive: the compound is the chloride salt of the coordination complex [Ni 2 Cl 2 (en) 4] 2+. This blue solid is soluble in water and some polar organic solvents.
The compound is synthesized by the reaction of cobalt(II) chloride and ethylenediamine in hydrochloric acid in the presence of oxygen: 4 CoCl 2 + 8 en + 4 HCl + O 2 → 4 trans-[CoCl 2 (en) 2]Cl + 2 H 2 O. The initial product contains HCl, which is removed by heating.
[1] [2] Mass spectra is a plot of relative abundance against mass-to-charge ratio. It is commonly used for the identification of organic compounds from electron ionization mass spectrometry. [3] [4] Organic chemists obtain mass spectra of chemical compounds as part of structure elucidation and the analysis is part of many organic chemistry ...
cis-Dichlorobis(ethylenediamine)cobalt(III) chloride is a salt with the formula [CoCl 2 (en) 2]Cl (en = ethylenediamine).The salt consists of a cationic coordination complex and a chloride anion.
A mass spectrum is a histogram plot of intensity vs. mass-to-charge ratio (m/z) in a chemical sample, [1] usually acquired using an instrument called a mass spectrometer. Not all mass spectra of a given substance are the same; for example, some mass spectrometers break the analyte molecules into fragments ; others observe the intact molecular ...
Bis(triphenylphosphine)palladium chloride is a coordination compound of palladium containing two triphenylphosphine and two chloride ligands. It is a yellow solid that is soluble in some organic solvents. It is used for palladium-catalyzed coupling reactions, e.g. the Sonogashira–Hagihara reaction. The complex is square planar. Many analogous ...
Cobalt(II) chloride is an inorganic compound, a salt of cobalt and chlorine, with the formula CoCl 2. The compound forms several hydrates CoCl 2 ·n H 2 O, for n = 1, 2, 6, and 9. Claims of the formation of tri- and tetrahydrates have not been confirmed. [4] The anhydrous form is a blue crystalline solid; the dihydrate is purple and the ...
