Disiamylborane (bis(1,2-dimethylpropyl)borane) is an organoborane with the formula [((CH 3) 2 CHCH(CH 3)) 2 BH] 2 (abbreviation: Sia 2 BH). It is a colorless waxy solid that is used in organic synthesis for hydroboration–oxidation reactions. Like most dialkyl boron hydrides, it has a dimeric structure with bridging hydrides.
[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.
1,1 ′-Bis(diphenylphosphino)ferrocene, commonly abbreviated dppf, is an organophosphorus compound commonly used as a ligand in homogeneous catalysis. It contains a ferrocene moiety in its backbone, and is related to other bridged diphosphines such as 1,2-bis(diphenylphosphino)ethane (dppe).
[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.
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(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.
Bis(cyclooctatetraenyl) complexes: M(C 8 H 8) 2, such as U(C 8 H 8) 2 and Th(C 8 H 8) 2 (both actinocenes). Metal– carborane complexes (metallacarboranes), a very large and diverse family in which main-group or transition metal ions are coordinated to carborane ligands to form polyhedral cages ranging in size from 6 to 15 vertices.
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.
