Two new Zr-based metal-organic frameworks [Zr6O4(OH)4(OAc)6(BDC)3] (CAU-26) and [Zr5O4(OH)4(OAc)4(BDC)2] (CAU-27) are reported, which were synthesized from HOAc, a rarely used but green and sustainable solvent (BDC2-: 1,4-benzenedicarboxylate). Structure determination aided by automated electron diffraction tomog. revealed that CAU-26 [Zr6O4(OH)4(OAc)6(BDC)3] is composed of layers of known {Zr6O8} clusters interconnected by terephthalate ions. In contrast CAU-27 [Zr5O4(OH)4(OAc)4(BDC)2] exhibits a three-dimensional structure with a so far unknown type of 1-dimensional inorganic building unit (IBU), which can be rationalized as condensed polyhedron-sharing chains of {Zr6O8} clusters. CAU-26 occurs as an intermediate of the CAU-27 synthesis and can be isolated easily, when reaction temperature and time are decreased. The authors were also able to synthesize two isoreticular derivatives of CAU-27 with extended linker mols. by implementing 4,4′-biphenyldicarboxylic acid (H2BPDC) and 5,5′-dicarboxy-2,2′-bipyridine (H2BIPY). All materials show high thermal and chem. stability as well as permanent microporosity. The excellent stability of CAU-27-BIPY was exploited to synthesize an Ir-supported heterogeneous MOF-based catalyst for the direct C-H borylation of arenes.

Mertins, Kristin; Zapf, Alexander; Beller, Matthias published an article in Journal of Molecular Catalysis A: Chemical. The title of the article was 《Catalytic borylation of o-xylene and heteroarenes via C-H activation》.Name: 2-(3,4-Dimethylphenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane The author mentioned the following in the article:

Ir and Rh complexes catalyze the borylation of xylene and different heteroarenes using pinacolborane via C-H activation. Various five-membered heterocycles such as thiophene, pyrrole, thionaphthene, and indole derivatives yield the borylated products in moderate to good yields. In general, the reactions proceed with high selectivity to give borylation ortho to the heteroatom.

Electric Literature of C14H21BO2On October 16, 2019 ,《Origin of the Difference in Reactivity between Ir Catalysts for the Borylation of C-H Bonds》 was published in Journal of the American Chemical Society. The article was written by Oeschger, Raphael J.; Larsen, Matthew A.; Bismuto, Alessandro; Hartwig, John F.. The article contains the following contents:

A mechanistic study on the origin of the difference in reactivity between Ir catalysts for C-H borylation reactions is reported. Catalytic reactions of B2pin2 with a series of substrates that require high temperatures and long reaction times were conducted. These reactions catalyzed by the combination of [Ir(COD)(OMe)]2 and 3,4,7,8-tetramethylphenanthroline (tmphen) occur in yields that are substantially higher than those of reactions catalyzed by [Ir(COD)(OMe)]2 and 4,4′-di-tert-butylbipyridine (dtbpy). The electronic properties of Ir catalysts ligated by dtbpy or tmphen and their stoichiometric reactivity were investigated. It was found that a longer lifetime rather than higher reactivity of the catalyst leads to higher yields of reactions catalyzed by Ir-tmphen. The catalyst ligated by dtbpy decomposes principally by dissociation of the ligand and rapid borylation at the positions alpha to nitrogen. Thus, the greater stability of the catalyst containing tmphen results from its greater binding constant In the experiment, the researchers used 2-(3,4-Dimethylphenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane(cas: 401797-00-0Electric Literature of C14H21BO2)

Application In Synthesis of 2-(3,4-Dimethylphenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolaneOn March 19, 2014, Obligacion, Jennifer V.; Semproni, Scott P.; Chirik, Paul J. published an article in Journal of the American Chemical Society. The article was 《Cobalt-Catalyzed C-H Borylation》. The article mentions the following:

A family of pincer-ligated cobalt complexes has been synthesized and are active for the catalytic C-H borylation of heterocycles and arenes. The cobalt catalysts operate with high activity and under mild conditions and do not require excess borane reagents. Up to 5000 turnovers for Me furan-2-carboxylate have been observed at ambient temperature with 0.02 mol % catalyst loadings. A catalytic cycle that relies on a cobalt(I)-(III) redox couple is proposed. The results came from multiple reactions, including the reaction of 2-(3,4-Dimethylphenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane(cas: 401797-00-0Application In Synthesis of 2-(3,4-Dimethylphenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane)
