And the article was included in Beilstein Journal of Organic Chemistry in 2007.Computed Properties of C8H7IO2 This article mentions the following:

M-Iodosylbenzoic acid is used to perform iodination of arenes in the presence of iodine at room temperature in acetonitrile. Separation of pure products is conveniently achieved by scavenging any aryl iodide by ion exchange with IRA-900 (hydroxide form). The reduced form of the reagent, m-iodobenzoic acid, can be easily recovered from the ion exchange resin or from the basic aqueous solution by simple acidification with HCl. In the experiment, the researchers used many compounds, for example, 3-Iodo-4-methoxybenzaldehyde (cas: 2314-37-6Computed Properties of C8H7IO2).

3-Iodo-4-methoxybenzaldehyde (cas: 2314-37-6) belongs to iodide derivatives. Typical reactions of alkyl iodides include nucleophilic substitution, elimination, reduction, and the formation of organometallics. 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.Computed Properties of C8H7IO2

Several homologous series of laterally halogenated and perfluoroalkyl- or perfluoroalkoxy-terminated tolanes derivatives were synthesized. Obtained compounds were divided into three families, i.e. tolanes, phenyltolanes, bistolanes and their mesomorphic properties, phase transition temperatures and enthalpies were determined The influence of the length of the core, type and position of substituents in the mol. core has been analyzed. The lack of aliphatic protons in mol. structure generates unique IR properties of presented materials and their mixtures In the experiment, the researchers used many compounds, for example, 1,2-Difluoro-3-iodobenzene (cas: 64248-57-3COA of Formula: C6H3F2I).

1,2-Difluoro-3-iodobenzene (cas: 64248-57-3) belongs to iodide derivatives. Organic iodides are organic compounds containing a carbon-iodine (C-I) bond. The carbon-iodine bond is weaker than other carbon-halogen bonds due to the poor electronegative nature of the iodine atom. A typical method for synthesis of aromatic iodides is diazotization of primary aromatic amines followed by treatment of potassium iodide. Aliphatic alcohols are converted to alkyl iodides by treating with hydrogen iodide.COA of Formula: C6H3F2I

And the article was included in ACS Catalysis in 2021.Recommanded Product: 4-Iodo-1,2-dimethoxybenzene This article mentions the following:

Modification of peptides via late-stage C-H activation is an emerging strategy to construct bioactive peptidomimetic libraries with expanded structural diversity for drug discovery. Peptides with thiazole motifs in the backbone as amide surrogates often exhibit improved bioactivity and biostability. However, methods to synthesize this class of compounds with structural diversity are limited. Here, we report the development of a highly versatile strategy for late-stage palladium-catalyzed C(sp³)-H arylation of peptides. This protocol utilizes the thiazole motifs in the peptide backbone as internal directing groups and allows the regio- and site-selective arylation of β-C(sp³)-H and γ-C(sp³)-H bonds in peptide side chains. The high biocompatibility of this method to functionalize and ligate peptides with a variety of aryl donors, biomols., and fluorophores sets the stage for efficient construction of peptide libraries with featured backbone thiazole units.

The development of a practical and highly convergent synthesis of an α_vβ₃ antagonist I is described. The two key fragments present in this compound, a chiral 3-aryl-5-oxopentanoic acid II and a tetrahydropyrido[2,3-b]azepine ring system III (R= Boc), were constructed independently and then coupled at a late stage using a Wittig reaction. The pyridoazepine moiety was prepared from N-Boc 6-chloro-2-aminopyridine via directed ortho-metalation/alkylation followed by in situ cyclization. A Suzuki reaction was then used to attach the propionaldehyde side-chain required for Wittig coupling. The coupling partner was prepared from asym. methanolysis of a 3-substituted glutaric anhydride followed by elaboration of the acid moiety to the requisite β-keto phosphorane. Using this route, kilogram quantities of the desired drug candidate were prepared In the experiment, the researchers used many compounds, for example, 1-Chloro-4-iodobutane (cas: 10297-05-9Reference of 10297-05-9).
