Uses

Different sources of media describe the Uses of 38932-80-8 differently. You can refer to the following data:
1. Tetrabutylammonium tribromide (TBATB) is a salt of the lipophilic tetrabutylammonium cation and the linear tribromide anion. It is used as a phase transfer catalyst in organic synthesis as well as a mild brominating agent. A wide range of O-isopropylidene derivatives can be prepared from the sugars and their derivatives on reaction with acetone at room temperature by employing 2 mol % of tetrabutylammonium tribromide as a catalyst. Good yields, low catalyst loading, mild reaction conditions, and a non-aqueous workup procedure are some major advantages of this protocol. Tetrabutylammonium tribromide as an efficient generator of HBr for an efficient chemoselective reagent for acetalization of carbonyl compounds. It is sometimes used as a reagent used in organic synthesis as a conveniently weighable, solid source of bromine. Tetra-n-butylammonium tribromide is useful for the preparation of vicinal dibromides from alkenes and alkynes and alfa-bromo acetals. it is utilized to generate hydrogen bromide, which is used as an efficient chemoselective reagent for acetalization of carbonyl compounds.
2. Tetrabutylammonium Tribromide is used in the synthesis of antimicrobial agents via chalcones. Also used in the synthesis of potent tubulin polymerization inhibitors.

Check Digit Verification of cas no

The CAS Registry Mumber 38932-80-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,8,9,3 and 2 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 38932-80:
(7*3)+(6*8)+(5*9)+(4*3)+(3*2)+(2*8)+(1*0)=148
148 % 10 = 8
So 38932-80-8 is a valid CAS Registry Number.

Polybromide salts of tetraalkyl and N-heterocyclic cations: New entries into the structural library

Gorokh, Igor D.,Adonin, Sergey A.,Sokolov, Maxim N.,Abramov, Pavel A.,Korolkov, Ilya V.,Semitut, Evgeniy Yu.,Fedin, Vladimir P.

, p. 583 - 587 (2018)

Reactions between Br2 dissolved in HBr and salts of various organic cations resulted in formation of a series of polyhalide salts: (IsoquinolH)Br3 (1), (2-BrPyH)Br3 (2), (H2(4,4′-bipy))(Br3)2 (3), Bu4NBr3 (4), (Collidinium){(Br3)(Br2)} (5) and Et4N{(Br3)(Br2)2} (6). All compounds were characterized by X-ray diffractometry; the role of supramolecular Br?Br contacts is discussed.

A Photorobust Mo(0) Complex Mimicking [Os(2,2′-bipyridine)3]2+and Its Application in Red-to-Blue Upconversion

Bilger, Jakob B.,Kerzig, Christoph,Larsen, Christopher B.,Wenger, Oliver S.

supporting information, p. 1651 - 1663 (2021/02/01)

Osmium(II) polypyridines are a well-known class of complexes with luminescent metal-to-ligand charge-transfer (MLCT) excited states that are currently experiencing a revival due to their application potential in organic photoredox catalysis, triplet-triplet annihilation upconversion, and phototherapy. At the same time, there is increased interest in the development of photoactive complexes made from Earth-abundant rather than precious metals. Against this background, we present a homoleptic Mo(0) complex with a new diisocyanide ligand exhibiting different bite angles and a greater extent of π-conjugation than previously reported related chelates. This new design leads to deep red emission, which is unprecedented for homoleptic arylisocyanide complexes of group 6 metals. With a 3MLCT lifetime of 56 ns, an emission band maximum at 720 nm, and a photoluminescence quantum yield of 1.5% in deaerated toluene at room temperature, the photophysical properties are reminiscent of the prototypical [Os(2,2′-bipyridine)3]2+ complex. Under 635 nm irradiation with a cw-laser, the new Mo(0) complex sensitizes triplet-triplet annihilation upconversion of 9,10-diphenylanthracene (DPA), resulting in delayed blue fluorescence with an anti-Stokes shift of 0.93 eV. The photorobustness of the Mo(0) complex and the upconversion quantum yield are high enough to generate a flux of upconverted light that can serve as a sufficiently potent irradiation source for a blue-light-driven photoisomerization reaction. These findings are relevant in the greater contexts of designing new luminophores and photosensitizers for use in red-light-driven photocatalysis, photochemical upconversion, light-harvesting, and phototherapy.

Process Development of the HCV NS5B Site D Inhibitor MK-8876

Williams, Michael J.,Chen, Qinghao,Codan, Lorenzo,Dermenjian, Renee K.,Dreher, Spencer,Gibson, Andrew W.,He, Xianliang,Jin, Yan,Keen, Stephen P.,Lee, Alfred Y.,Lieberman, David R.,Lin, Wei,Liu, Guiquan,McLaughlin, Mark,Reibarkh, Mikhail,Scott, Jeremy P.,Strickfuss, Sophie,Tan, Lushi,Varsolona, Richard J.,Wen, Feng

, p. 1227 - 1238 (2016/07/23)

We describe the route development and multikilogram-scale synthesis of an HCV NS5B site D inhibitor, MK-8876. The key topics covered are (1) process improvement of the two main fragments; (2) optimization of the initially troublesome penultimate step, a key bis(boronic acid) (BBA)-based borylation; (3) process development of the final Suzuki-Miyaura coupling; and (4) control of the drug substance form. These efforts culminated in a 28 kg delivery of the desired active pharmaceutical ingredient.
