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').
The structure of chromocene has been verified by X-ray crystallography.The average Cr–C bond length is 215.1(13) pm. [6] Each molecule contains an atom of chromium bound between two planar systems of five carbon atoms known as cyclopentadienyl (Cp) rings in a sandwich arrangement, which is the reason its formula is often abbreviated as Cp 2 Cr.
Bis(trimethylsilyl)acetamide (BSA) is an organosilicon compound with the formula MeC(OSiMe 3)NSiMe 3 (Me = CH 3). It is a colorless liquid that is soluble in diverse organic solvents, but reacts rapidly with moisture and solvents containing OH and NH groups .
[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.
[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.
[2] [7] BPA is produced on an industrial scale by the condensation reaction of phenol and acetone. Global production in 2022 was estimated to be in the region of 10 million tonnes. [8] BPA's largest single application is as a co-monomer in the production of polycarbonates, which accounts for 65–70% of all BPA production.
1,1-Bis(diphenylphosphino)methane (dppm), is an organophosphorus compound with the formula CH 2 (PPh 2) 2. Dppm, a white, crystalline powder, is used in inorganic and organometallic chemistry as a ligand. [1] It is more specifically a chelating ligand because it is a ligand that can bond to metals with two phosphorus donor atoms.
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.
