The numbers 200-900 would be confused easily with 22 to 29 if they were used in chemistry. khīlioi = 1000, diskhīlioi = 2000, triskhīlioi = 3000, etc. 13 to 19 are formed by starting with the Greek word for the number of ones, followed by και (the Greek word for 'and'), followed by δέκα (the Greek word for 'ten').
Magnesocene is a white solid at room temperature. [1] It has a melting point of 176 °C, though at atmospheric pressures it sublimes at 100 °C. [1] Unlike ferrocene, magnesocene displays slight dissociation and subsequent ion association in polar, electron-donating solvents (such as ether and THF).
Bis(triphenylphosphine)platinum chloride is a metal phosphine complex with the formula PtCl 2 [P(C 6 H 5) 3] 2. Cis- and trans isomers are known. The cis isomer is a white crystalline powder, while the trans isomer is yellow. [3] Both isomers are square planar about the central platinum atom. The cis isomer is used primarily as a reagent for ...
[1] [2] 5 C 6 H 5 MgBr + 4 CrCl 3 → (C 6 H 5) 5 CrBr + 2 MgBr 2 + 3 MgCl 2 + 3 CrCl 2. This event marked an advance in organochromium chemistry at the time and "(C 6 H 5) 5 CrBr" was described to have salt-like properties. However, the reported workup procedures for "(C 6 H 5) 5 CrBr" was challenging and the yield was low.
[Mg(η 5-C 5 H 5) 2] named bis(η 5-cyclopentadienyl)magnesium, or bis(η 5-cyclopentadienido)magnesium; Na(CHCH 2) sodium ethenide (compositional name) However the recommendation notes that future nomenclature projects will be addressing these compounds.
Synthesis of bis(2-ethylhexyl)-tetrabromophthalate (TBPH) from tetrabromophthalic anhydride and 2-ethylhexanol. In this general synthesis method, tetrabromophthalic anhydride and 2-ethylhexanol are used as raw materials in a molar mass ratio of 3-7:1.
As a chelating ligand, 1,1-bis(diphenylphosphino)methane forms a four-membered ring with the constituents MP 2 C. The ligand promotes the formation of bimetallic complexes that feature five-membered M 2 P 2 C rings. In this way, dppm promotes the formation of bimetallic complexes. One such example is the dipalladium chloride, Pd 2 Cl 2 (dppm) 2.
[1] [2] [3] Most are based on two hydroxyphenyl functional groups linked by a methylene bridge. Exceptions include bisphenol S, P, and M. "Bisphenol" is a common name ; the letter following denotes the variant, which depends on the additional substituents.
