Campbell, James B. published the artcileAddition of Transiently-Generated Methyl o-Lithiobenzoate to Imines. An Isoindolone Annulation, Formula: C10H9IO4, the publication is Journal of Organic Chemistry (1996), 61(18), 6205-6211, database is CAplus and MEDLINE.

Addition of phenyllithium to a mixture of an imine, Me o-iodobenzoate, and BF₃·etherate at -105 °C gave good to excellent yields of isoindolones. A transient formation of Me o-lithiobenzoate was proposed, which is formed by a rapid lithium/iodide exchange reaction of the phenyllithium with Me o-iodobenzoate in the presence of an imine. For example, lithiation of N-methylbenzamide gave the lithiate I which upon treatment with imines gave 2-ethyl-2,3-dihydro-3-phenyl-1H-isoindol-1-ones II (R¹ = alkyl, phenyl; R² = Ph, propyl). The transiently generated anions were captured by the BF₃-activated imines to form the isoindolones in good to high yield. The reactions conditions are sufficiently mild, and selective, to permit functional groups such carbmethoxy and aryl bromide, which could otherwise react with the added PhLi, to be tolerated.

Lammert, Martin published the artcileSingle- and Mixed-Linker Cr-MIL-101 Derivatives: A High-Throughput Investigation, Product Details of C10H9IO4, the publication is Inorganic Chemistry (2013), 52(15), 8521-8528, database is CAplus and MEDLINE.

New single- and mixed-linker Cr-MIL-101 derivatives bearing different functional groups were synthesized. The influence of the reaction parameters, such as metal source (CrO₃, CrCl₃, and Cr(NO₃)₃·9H₂O) or linker composition, on product formation were studied using high-throughput methods. Highly crystalline Cr-MIL-101 materials were obtained with CrCl₃ as the metal source with either 2-bromoterephthalic (TA-Br) or 2-nitroterephthalic (TA-NO₂) acid as one of the mixed-linker components. Numerous new mixed-linker Cr-MIL-101 derivatives containing -NH₂, -NO₂, -H, -SO₃H, -Br, -OH, -CH₃, and -COOH were synthesized. The use of TA-NH₂ and TA-OH were shown, under the same reaction conditions, to lead to decarboxylation and the formation of 3-amino- and 3-hydroxybenzoic acid, resp. Also, the authors were also able to directly synthesize single-linker Cr-MIL-101-X derivatives with X = F, Cl, Br, CH₃. Postsynthetic modification was used to selectively reduce the mixed-linker compound Cr-MIL-101-Br-NO₂ to Cr-MIL-101-Br-NH₂. To establish the successful incorporation of the linker mols. and possible decomposition of certain starting materials, ¹H NMR spectra of dissolved reaction products were recorded.

Ivan, nathaniel published the artcileSynthesis of new boronated and phosphonated aromatic flame retardants, Computed Properties of 165534-79-2, the publication is PMSE Preprints (2012), No pp. given, database is CAplus.

We have focused on the use of catalytic processes to add boron and phosphorus based groups to aromatic compounds such as terephthalates and phenols. This has been done since these compounds could in turn act as reactive flame retardants which could address some of the environmental/leaching issues that affect flame retardant materials.

Ivan, Nathaniel published the artcilePreparation of phosphonoterephthalic acids via palladium-catalyzed coupling of aromatic iodoesters, Computed Properties of 165534-79-2, the publication is Synthetic Communications (2013), 43(13), 1831-1836, database is CAplus.

The current article reported in detail the preparation of two phosphonoterephthalic acids: 2-phosphonoterephthalic acid and 2,5-diphosphonoterephthalic acid. Efficient, scalable syntheses were developed for both compounds based on Pd-catalyzed coupling reactions of iodinated terephthalate esters. Phosphonoterephthalic acids are potentially useful as flame-retardant additives or as monomers for the construction of acid-pendant polymer chains.

Cartagenova, Daniele published the artcileHighly selective Suzuki reaction catalyzed by a molecular Pd-P-MOF catalyst under mild conditions: role of ligands and palladium speciation, Category: iodides-buliding-blocks, the publication is Catalysis Science & Technology (2022), 12(3), 954-961, database is CAplus.

A molecularly-defined heterogeneous palladium catalyst based on a phosphine-metal-organic framework (P-MOF) ligand system was reported. This catalyst performed Suzuki reactions of aryl bromides and Ph boronic acid to afford biaryls R-R¹ [R = Ph; R¹ = 3-MeC₆H₄, 3-OMeC₆H₄, 3-pyridyl, etc.] in exceptionally mild conditions while displayed a unique selectivity, higher than that achieved using Pd(PPh₃)₄, a standard homogeneous catalyst. The new palladium P-MOF catalyst was active for a wide range of substrates. Determination of the palladium speciation showed that molecularly-defined palladium-phosphine sites catalyzed the Suzuki cross-coupling with very high selectivity, and that, when formed, palladium nanoparticles promoted hydrodehalogenation. The fraction of molecularly defined palladium was maximized by having excess of phosphine ligand in the system.
