A palladium-catalyzed C-H iodination of unactivated alkenes is reported. A picolinamide directing group enables the regioselective functionalization of a wide array of olefins to furnish iodination products as single stereoisomers. Mechanistic studies suggest the reversible formation of a six-membered alkenyl palladacycle intermediate through a turnover-limiting C-H activation.

Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Journal of the Chemical Society [Section] A: Inorganic, Physical, Theoretical called Bridge-splitting reactions and far infrared spectra of diene derivatives of palladium(II) and platinum(II) complexes, Author is Crociani, Bruno; Uguagliati, Paolo; Boschi, Tristano; Belluco, Umberto, which mentions a compound: 12266-72-7, SMILESS is I[Pt]I.C1=CCC/C=CCC/1, Molecular C8H12I2Pt, Related Products of 12266-72-7.

Bridge-splitting reactions of complexes of the type [M(diene.OMe)X]2 (M = Pd(II), Pt(II); diene = cycloocta-1,5-diene, dicyclopentadiene; X = Cl, Br) by neutral ligands (L) having N or P as donor atoms are reported. For the products [M(diene.OMe)LX] two structures are possible, i.e., with L cis to the olefinic double bond (A) or trans to it (B). On the basis of far-ir, spectra, structure (A) has been attributed to [Pd(diene.OMe)(py)Cl] and [Pt(diene.-OMe)LX)] (L = pyridine and p-toluidine). Structure (B) has been attributed to [Pt(diene.OMe)(PPh3)X] and to the analogous Pd(II) complexes. From [M(diene.OMe)(py)Cl] the pyridine is displaced by another neutral ligand, whereas the chloride ion is displaced only by an anionic one. The far-ir spectra (500-60 cm.-1) of the dimers [M(diene.OMe)X]2 are reported and the metal-bridging halogen stretching frequencies are assigned on the basis of a Cipoint-group symmetry. The v(M-Clbridging) falls in the range 298-216 cm.-1, v(M-Brbridging 201-148 cm.-1, and v(M-Ibridging) 165-122 cm.-1

In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Modulatory Effect of Indoles on the Expression of miRNAs Regulating G1/S Cell Cycle Phase in Breast Cancer Cells, published in 2020-12-31, which mentions a compound: 1968-05-4, Name is 3,3′-Diindolylmethane, Molecular C17H14N2, Safety of 3,3′-Diindolylmethane.

Indole-3-carbinol (I3C) is a naturally occurring glucosinolate found in Brassica vegetables that is usually converted in gastric acidic environment to the efficient metabolite 3,3′-diindolylmethane (DIM). Both indoles (I3C and DIM) are known chemopreventive agents for various cancers including breast cancer. This study aimed to investigate the influence of both indoles on the tumor suppressor miRNAs (let-7a-e, miR-15a, miR-16, miR-17-5p, miR-19a, and miR-20a) and oncomiRs (miR-181a, miR-181b, miR-210, miR-221, and miR-106a), which are controlling the cell cycle key regulators: cyclin-dependent kinases (CDKs), CDK inhibitor p27Kip1, and cyclin D1. Our results indicated that both indoles generally elevated the expression of the tumor suppressor miRNAs let-7a-e, miR-19a, miR-17-5p, and miR-20a and decreased the expression of the oncomiR list. Both indoles were able to significantly suppress the expression of CDK4 and CDK6 as well as the apoptotic markers Bcl-2 and survivin. Both indoles decreased cyclin-D1 protein, where I3C decreased cytoplasmic and nuclear cyclin-D1 significantly. Cytoplasmic and nuclear P27Kip1 showed overexpression following treatment with I3C higher than that detected following DIM treatment. This study provides a mechanistic elucidation of the previously reported cell cycle arrest by I3C and DIM in breast cancer cells suggesting that this effect could be through modulation of miRNAs expression that, in turn, regulates the genetic network controlling the G1/S phase in cell cycle progression.

So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Bergamini, Paola; Costa, Emiliana; Sostero, Silvana; Ganter, Christian; Hogg, John; Orpen, A.

So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Skauge, Andrew R. L.; Shalders, Richard D.; Swaddle, Thomas W. researched the compound: Diiodo(1,5-cyclooctadiene)platinum(II)( cas:12266-72-7 ).Application of 12266-72-7.They published the article 《High-pressure methods as a tool in organometallic syntheses: facilitation of oxidative addition to platinum(II)》 about this compound( cas:12266-72-7 ) in Canadian Journal of Chemistry. Keywords: high pressure oxidative addition platinum; alkyl iodide oxidative addition platinum pressure; volume activation oxidative addition platinum. We’ll tell you more about this compound (cas:12266-72-7).

High-pressure (2 GPa) batch reactors now com. available may offer substantial accelerations of organometallic syntheses, without resort to heating, when the activation process is multicentered or involves the generation and solvation of ions. As an example of the latter class of reactions, the kinetics of the oxidative additions of Me and Et iodides (RI) to dimethyl(2,2′-bipyridine)platinum(II) in acetone were studied over the pressure range 0-200 MPa. The volumes of activation ΔV1⧧, if assumed to be constant over this range, are -11.7 ± 0.3 and -9.7 ± 0.7 cm3 mol-1, resp., implying an acceleration of ∼3000-fold for a batch synthesis of this sort at 2 GPa. However, a possible slight pressure dependence of ΔV1⧧ may reduce this acceleration to ∼1,000-fold. The ΔV1⧧ data and the 500-fold retardation on going from R = Me to R = Et are consistent with an SN2 attack of PtII on the α-C in the alkyl iodides, forming I- and [RMe2Pt(bpy)]+.
