ortho-Carborane undergoes 2e- reduction when treated with a solution of lithium in ammonia. The result is the nido cluster 7,9-[C 2 B 10 H 12] 2-. In the dianion, the carbon vertices are not adjacent. The same cluster is produced by reduction of meta-carborane. Oxidation of the resulting 7,9-[C 2 B 10 H 12] 2-gives ortho-carborane. [4]
The icosahedral charge-neutral closo-carboranes, 1,2-, 1,7-, and 1,12- C 2 B 10 H 12 (informally ortho-, meta-, and para-carborane) are particularly stable and are commercially available. [10] [11] The ortho-carborane forms first upon the reaction of decaborane and acetylene. It converts quantitatively to the meta-carborane upon heating in an ...
One example is [B 12 (CH 3) 12] 2-and its radical derivative [B 12 (CH 3) 12] −. [16] Related cluster compounds with carbon vertices are carboranes; the best known is orthocarborane, C 2 B 10 H 12. Carboranes have few commercial applications. Anionic derivatives such as [C 2 B 9 H 11] 2−, called dicarbollides, ligate similarly to ...
In organoboron chemistry, a carboryne is an unstable derivative of ortho-carborane with the formula B 10 C 2 H 10. [1] They are also called 1,2-dehydro-o-carboranes. The hydrogen atoms on the C2 unit in the parent o-carborane are missing. The compound resembles and is isolobal with benzyne.
o-Phenylenediamine (OPD) is an organic compound with the formula C 6 H 4 (NH 2) 2. This aromatic diamine is an important precursor to many heterocyclic compounds. OPD is a white compound although samples appear darker owing to oxidation by air. It is isomeric with m-phenylenediamine and p-phenylenediamine.
A further example of insertion into a closo carborane is the synthesis of the yellow-orange solid closo-1,2,3-(CO) 3 FeC 2 B 4 H 6: closo−C 2 B 4 H 8 + Fe 2 (CO) 9 → closo−(CO) 3 FeC 2 B 4 H 6 + Fe(CO) 5 + CO. A closely related reaction involves the capping of an anionic nido carborane C 2 B 4 H − 7. closo−C 2 B 4 H 8 + NaH → Na ...
α-Propylphenethylamine (APPEA or α-Pr-PEA), also known as 1-phenyl-2-aminopentane, is a stimulant drug of the phenethylamine and amphetamine families. [1] [2] It is the analogue of the β-phenethylamine (PEA) derivatives amphetamine (α-methylphenethylamine; "AMPEA") and phenylisobutylamine (α-ethylphenethylamine; AEPEA) in which the α-alkyl chain has been further lengthened to be a propyl ...
All three isomers have the chemical formula C 6 H 6 O 2. Similar to other phenols, the hydroxyl groups on the aromatic ring of a benzenediol are weakly acidic . Each benzenediol can lose an H + from one of the hydroxyls to form a type of phenolate ion.
