19821-80-8 Usage

General Description

1,3-Dibromo-2-iodobenzene is an organic compound, more specifically an aromatic bromide, with the molecular formula C6H3Br2I. This formula indicates the presence of two bromine (Br) and one iodine (I) atom attached to a benzene ring, which is a cyclic compound consisting of six carbon (C) atoms. The "1,3-dibromo-2-iodo" prefix in its name refers to the position of these halogens on the benzene ring. Like other aromatic bromides, it generally exhibits high stability and low reactivity. This chemical could potentially be used in various applications such as medicinal chemistry, organic synthesis, and materials science, but should be handled carefully due to its harmful nature.

Check Digit Verification of cas no

The CAS Registry Mumber 19821-80-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,8,2 and 1 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 19821-80:
(7*1)+(6*9)+(5*8)+(4*2)+(3*1)+(2*8)+(1*0)=128
128 % 10 = 8
So 19821-80-8 is a valid CAS Registry Number.

Two unprecedented porphyrin fused nanographene molecules, 1 and 2, have been synthesized by the Scholl reaction from tailor-made precursors based on benzo[m]tetraphene-substituted porphyrins. The chemical structures were validated by a combination of high

Synthesis and Physical Properties of Strained Doubly Phosphorus-Bridged Biaryls and Viologens

Greulich, Tobias W.,Yamaguchi, Eriko,Doerenkamp, Carsten,Lübbesmeyer, Maximilian,Daniliuc, Constantin G.,Fukazawa, Aiko,Eckert, Hellmut,Yamaguchi, Shigehiro,Studer, Armido

, p. 6029 - 6033 (2017)

New P/N-containing π-electron systems comprising fully planar biaryl arrays are synthesized by multiple radical phosphanylation. The biaryl moiety in these highly strained planar π-systems is rigidified by double P-bridging. The electronic properties of the core biaryl entity are varied by introducing N-donor substituents or by installing N-atoms within the π-system, thereby moving to the viologen core structure. The electrochemical and photophysical properties of these compounds are discussed and compared with those of related systems.

The "Aryne" route to biaryls featuring uncommon substituent patterns

Leroux, Frederic,Schlosser, Manfred

, p. 4272 - 4274 (2002)

1,2-Didehydroarenes ("arynes") mediate as extremely reactive, short-lived intermediates in selective aryl-aryl coupling processes to form biaryls with unprecedented substituent patterns (see scheme, X = H, F, Cl). Possible applications include the synthesis of novel ligands for asymmetric catalysis.

Synthetic method for optically pure double-helix oligomeric tetra-benzocyclooctene substances

-

Paragraph 0045; 0046, (2017/07/31)

The invention discloses a synthetic method for optically pure double-helix oligomeric tetra-benzocyclooctene substances. The synthetic method comprises the following steps: (1) carrying out oxidative cross-coupling on diiodo dimethoxy biphenyl (51) and 2,2',6,6'-biphenyl tetrabromide (97) to obtain 1,16-dibromo-8,9-dimethoxy tetra-benzocyclooctene (96); (2) splitting the compound (96), thus obtaining optically pure (S, S)-96 and (R, R)-96; (3) taking the compound (96) as a raw material, synthesizing an intermediate (116) containing 6 benzene rings; (4) splitting the intermediate (116) to obtain (M)-116 and (P)-116; (5) making the optically pure (S, S)-96 and (M)-116 reacted to obtain target products, namely (M) -117, (M)-149 and (M)-150; and/or: making the (R, R)-96 and (P)-116 reacted to obtain target products, namely (P)-117, (P)-149 and (P)-150.
