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').
Bis(pinacolato)diboron is a covalent compound containing two boron atoms and two pinacolato ligands. It has the formula [(CH 3) 4 C 2 O 2 B] 2; the pinacol groups are sometimes abbreviated as "pin", so the structure is sometimes represented as B 2 pin 2. It is a colourless solid that is soluble in organic solvents.
-bis, an IUPAC numerical multiplier for compound or complex features, meaning 2; A colloquial name for N,N'-Methylenebisacrylamide; Barratt Impulsiveness Scale, in psychology; Behavioural Inhibition System, a brain-behavioral systems in reinforcement sensitivity theory; BIS monitor or bispectral index, to assess the depth of anaesthesia
3 (phosphonate) groups covalently linked to carbon determine both the name "bisphosphonate" and the function of the drugs. Bis refers to the fact that there are two such groups in the molecule. The long side-chain (R 2 in the diagram) determines the chemical properties, the mode of action and the strength of bisphosphonate drugs.
This reaction is degenerate and, in the jargon of organic chemistry, it is an example of a sigmatropic rearrangement. [citation needed] A related example is Bis(cyclooctatetraene)iron, in which the η 4 - and η 6-C 8 H 8 rings interconvert. Case 2, typically: complexes containing cyclic polyhapto ligands with maximized hapticity. Such ligands ...
Triphenylbismuth, an example of an organometallic bismuth(III) compound. Organobismuth chemistry is the chemistry of organometallic compounds containing a carbon to bismuth chemical bond. Applications are few. [1] [2] The main bismuth oxidation states are Bi(III) and Bi(V) as in all higher group 15 elements.
The [BAr F 4] − anion with four fluorinated aryl groups distributed tetrahedrally about a central boron atom. Tetrakis[3,5-bis(trifluoromethyl)phenyl]borate is an anion with chemical formula [{3,5-(CF 3) 2 C 6 H 3} 4 B] −, which is commonly abbreviated as [BAr F 4] −, indicating the presence of fluorinated aryl (Ar F) groups.
Examples include BT-Epoxy, which is one of a number of resins used in the production of printed circuit boards. Polyetherimides such as Ultem can be produced from BPA via a nitro-displacement of appropriate bisnitroimides. [51] [52] These thermoplastic polyimide plastics have exceptional resistance to mechanical, thermal and chemical damage ...
