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').
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.
For example: Me 3 Bi + SO 2 Cl 2 → Me 3 BiCl 2 + SO 2 Me 3 BiCl 2 + 2 MeLi → Me 5 Bi + 2 LiCl. Unstable, purple Ph 5 Bi was the first to be synthesized so. [6] Bi(V) easily forms an onium ion for example by protonation with p-toluenesulfonic acid: [19] Ph 5 Bi + HO 3 SAr → Ph 4 Bi + [O 3 SAr −] Pentaphenylbismuth forms an ate complex ...

Bisphenols A (BPA), F (BPF) and S (BPS) have been shown to be endocrine disruptors, potentially relating to adverse health effects. [3] [6] Due to its high production volumes, BPA has been characterised as a "pseudo-persistent" chemical, [7] leading to its spreading and potential accumulation in a variety of environmental matrices, even though it has a fairly short half-life.
Bis(2-ethylhexyl) phthalate (di-2-ethylhexyl phthalate, diethylhexyl phthalate, diisooctyl phthalate, DEHP; incorrectly — dioctyl phthalate, DIOP) is an organic compound with the formula C 6 H 4 (CO 2 C 8 H 17) 2. DEHP is the most common member of the class of phthalates, which are used as plasticizers.
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.
Sodium bis(2-methoxyethoxy)aluminium hydride (SMEAH; [1] trade names Red-Al, Synhydrid, Vitride) is a hydride reductant with the formula NaAlH 2 (OCH 2 CH 2 OCH 3) 2. The trade name Red-Al refers to its being a red ucing al uminium compound.
