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(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 .
[5] [10] [11] [12] Long-term treatment with bisphosphonates produces anti-fracture and bone mineral density effects that persist for 3–5 years after an initial 3–5 years of treatment. [ 2 ] The bisphosphonate alendronate reduces the risk of hip, vertebral, and wrist fractures by 35-39%; zoledronate reduces the risk of hip fractures by 38% ...
These components are assembled by means of copper(I) catalyzed alkyne-azide cycloaddition (CuAAC, also known as Huisgen reaction, a Click chemistry reaction), giving rise to the three 1,3-triazole linkages in the 68 Ga-Trivehexin structure. [1]
Nomenclature of Inorganic Chemistry, IUPAC Recommendations 2005 is the 2005 version of Nomenclature of Inorganic Chemistry (which is informally called the Red Book). It is a collection of rules for naming inorganic compounds, as recommended by the International Union of Pure and Applied Chemistry (IUPAC).
The complex is a prototype of a large family of bis complexes or the formula Ni(S 2 C 2 R 2) 2 (R = H, alkyl, aryl). These complexes have attracted much attention as dyes . They are of academic interest because the dithiolenes are noninnocent ligands . [ 2 ]
Some diphosphines, such as the extraordinary case of t Bu 2 P(CH 2) 10 P t Bu 2, give macrocyclic complexes with as many as 72 atoms in a ring. [ 7 ] To position phosphine donor groups trans on a coordination sphere, several atoms are required to link the donor centres and long-chain diphosphines are typically floppy and do not chelate well.
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.
