Porous mol. crystals are an emerging class of porous materials that is unique in being built from discrete mols. rather than being polymeric in nature. In this study, we examined the effects of mol. structure of the precursors on the formation of porous solid-state structures with a series of 16 rigid aromatics The majority of these precursors possess pyrazole groups capable of hydrogen bonding, as well as electron-rich aromatics and electron-poor tetrafluorobenzene rings. These precursors were prepared using a combination of Pd- and Cu-catalyzed cross-couplings, careful manipulations of protecting groups on the nitrogen atoms, and solvothermal syntheses. Our study varied the geometry and dimensions of precursors, as well as the presence of groups capable of hydrogen bonding and [π···π] stacking. Thirteen derivatives were crystallog. characterized, and four of them were found to be porous with surface areas between 283 and 1821 m² g^-1. Common to these four porous structures were (a) rigid trigonal geometry, (b) [π···π] stacking of electron-poor tetrafluorobenzenes with electron-rich pyrazoles or tetrazoles, and (c) hydrogen bonding between the terminal heteroaromatic rings. In the experiment, the researchers used many compounds, for example, 1,4-Diiodo-2,3,5,6-tetramethylbenzene (cas: 3268-21-1Electric Literature of C10H12I2).

1,4-Diiodo-2,3,5,6-tetramethylbenzene (cas: 3268-21-1) belongs to iodide derivatives. Generally organic iodides can be divided into two classes of alkyl iodides and aryl iodides. Typical reactions of alkyl iodides include nucleophilic substitution, elimination, reduction, and the formation of organometallics. In the chemical industry, alkyl iodides serve as excellent alkylating agents and, specifically, methyl iodide is used as a methylating agent in the synthesis of various pharmaceutical drugs.Electric Literature of C10H12I2

A tandem reaction involving an intramol. oxypalladation of an alkyne and an addition to the carbonyl group to quench the carbon-palladium bond to complete the catalytic cycle was developed. The reaction of 2-alkynylphenols with aldehydes to prepare substituted 3-(hydroxymethyl)benzofurans in one pot is described. E.g, reaction of 2-(phenylethynyl)phenol and p-nitrobenzaldehyde, catalyzed by [Pd(dppp)(H₂O)₂](BF₄)₂, gave 90% benzofuran (I). The reaction was catalyzed with the cationic palladium(II) species without the necessity of a redox system. In the experiment, the researchers used many compounds, for example, 4-Bromo-2-iodophenol (cas: 207115-22-8Electric Literature of C6H4BrIO).

4-Bromo-2-iodophenol (cas: 207115-22-8) belongs to iodide derivatives. Organic iodides can be alkyl, alkenyl, or alkynyl, and all of them are very reactive toward with many kinds of nucleophiles. The C–I bond is the weakest of the carbon–halogen bonds. These bond strengths correlate with the electronegativity of the halogen, decreasing in the order F > Cl > Br > I. This periodic order also follows the atomic radius of halogens and the length of the carbon-halogen bond.Electric Literature of C6H4BrIO

Efficient Asymmetric Synthesis of Biologically Important Tryptophan Analogues via a Palladium-Mediated Heteroannulation Reaction was written by Ma, Chunrong;Liu, Xiaoxiang;Li, Xiaoyan;Flippen-Anderson, Judith;Yu, Shu;Cook, James M.. And the article was included in Journal of Organic Chemistry in 2001.HPLC of Formula: 220185-63-7 This article mentions the following:

A novel and concise synthesis of optically active tryptophan derivatives was developed via a palladium-catalyzed heteroannulation reaction of substituted o-iodoanilines with an internal alkyne. The required internal alkyne I was prepared in greater than 96% diastereomeric excess via alkylation of the Schollkopf chiral auxiliary, 3,6-diethoxy-2R-isopropyl-2,5-dihydropyrazine with Me₃SiCCCH₂OP(:O)(OPh)₂. Similarly, alkyne II was obtained from the alkylation of 3,6-diethoxy-2S-isopropyl-2,5-dihydropyrazine by TMSCCCH₂OP(:O)(OPh)₂. I was used as an intermediate in the palladium-catalyzed heteroannulation reaction to afford L-tryptophan analogs, whereas II afforded D-tryptophan analogs. Using this strategy, the first asym. syntheses of L-isotryptophan (III) and L-benz[f]tryptophan (IV) were realized. In addition, the optically pure Et 6-methoxy-D-tryptophanate (V) was prepared by this protocol on a large scale (>300 g). An improved total synthesis of tryprostatin A (VI) was accomplished in 43% overall yield employing this palladium-mediated process. In the experiment, the researchers used many compounds, for example, 4,5-Dichloro-2-iodoaniline (cas: 220185-63-7HPLC of Formula: 220185-63-7).

Polyiodoorganic compounds are sometimes employed as X-ray contrast agents, in fluoroscopy, a type of medical imaging. This application exploits the X-ray absorbing ability of the heavy iodine nucleus.HPLC of Formula: 220185-63-7

Five-State Rotary Nanoswitch was written by Gaikwad, Sudhakar;Schmittel, Michael. And the article was included in Journal of Organic Chemistry in 2017.Computed Properties of C10H12I2 This article mentions the following:

In our quest to develop artificial multistate devices, we synthesized the nanomech. switch 1 that is characterized by a tetrahedral core equipped with four pending arms. The rotary arm with its azaterpyridine terminal is intramolecularly coordinated to a zinc(II) porphyrin station that is the terminus of another arm in 1. The two other arms carry identical sterically shielded phenanthroline stations. The 2-fold alternate addition of a copper(I) ion and [1,10]-phenanthroline (1 equiv each) results in the formation of five different switching states (State Iâ†?State IIâ†?State IIIâ†?State IVâ†?State V â†?State I), which force the toggling arm to move back and forth between the zinc(II) porphyrin and phenanthroline stations separated by a distance of 25 Å. All switching states constitute clean single species, except for State III, and thus are fully characterized by spectroscopic methods and elemental anal. Finally, the initial state of nanoswitch was reset by addition of cyclam for complete removal of the copper(I) ions. In the experiment, the researchers used many compounds, for example, 1,4-Diiodo-2,3,5,6-tetramethylbenzene (cas: 3268-21-1Computed Properties of C10H12I2).
