In heterogeneous catalysis, the catalyst is in a different phase from the reactants. Computed Properties of C8H7NO3, At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. 17403-47-3, name is 5-Nitro-2,3-dihydrobenzofuran. In an article，Which mentioned a new discovery about 17403-47-3

Because they are a potential source of valuable structural information, experimental and theoretical results are reported for the bond-order, conformational, and substituent dependencies of the long range H – H coupling constants over four bonds (orthobenzylic coupling, Job) between protons on an sp3-hybridized alpha-carbon atom and the ortho protons of aromatic systems.A large number of methyl aromatic systems were synthesized and their coupling constants were accurately measured.The best correlations in this series of compounds were with the square of the mobile ?-bond order and with the mutual atom-atom polarizability ?rhorho’.In addition, several series of compounds with defined geometries and a range of dihedral angles were synthesized and the 1H NMR parameters were measured.The best agreement of the data is with a semiempirical equation, which relates the orthobenzylic coupling constant to ?rhorho’ and to dihedral angles according to the equation Job(phi, ?rhorho’) = 6.90 ?rhorho’ sin2phi – 0.32 cos2phi Hz.Substituent effects on Job are not usually important; exceptions are found in the 1-substituted acenaphthene derivatives, in which Job becomes more positive with increasing electronegativity, and in ring-substituted toluenes, having both a nitro and an oxygen group which exert significant bond-fixing effects.

Synthetic Route of 54109-03-4, Because a catalyst decreases the height of the energy barrier, its presence increases the reaction rates of both the forward and the reverse reactions by the same amount.54109-03-4, Name is 5-Chloroisobenzofuran-1(3H)-one, molecular formula is C8H5ClO2. In a article，once mentioned of 54109-03-4

Copper-catalysed N-arylation of pyrazoles with aryl or heteroaryl bromides or iodides, which can include functional substituents, was performed under the mildest conditions yet described, with excellent yields and selectivity, by the use as catalyst of a combination of cuprous oxide with a set of inexpensive, chelating oxime-type ligands not previously known to promote such reactions. Other original bi-, tri- or tetradentate ligands providing nitrogen and/or oxygen as chelating atoms were also successfully tested in this type of arylation. ( Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2004).

Two concise syntheses of (+/-)-frondosin B (1), an interleukin-8 receptor antagonist, have been achieved from commercially available 5-methoxysalicylaldehyde. The seven-membered ring in ketone 33, the common intermediate for both syntheses, was built by a classical Friedel-Crafts reaction. The key step of the first route was facile cationic cyclization of the vinylogous benzofuran to the trisubstituted olefin (30 -> 16 + 38) to construct a six-membered carbocycle. Although this route demonstrated the efficacy of the stepwise approach to the frondosin ring-system, it also resulted in olefinic isomers that were easily isomerized in acidic conditions. in the second route, we utilized a Diels-Alder reaction between sterically demanding diene 42 and nitroethylene to fix the double bond in its required position in the resultant dimethylcyclohexane ring. A third total synthesis was devised for the purpose of determining the absolute configuration of frondosin B. It reached diene 42, this time in the enantiomerically defined form. From this point, naturally configured frondosin B was obtained in the enantiomerically enriched form. These studies establish the absolute configuration of the secondary methyl center in frondosin B to be R.

In homogeneous catalysis, the catalyst is in the same phase as the reactant. The number of collisions between reactants and catalyst is at a maximum.In a patent, 24673-56-1, name is 3-Methylbenzofuran-2-carboxylic acid, introducing its new discovery. Computed Properties of C10H8O3

Aryl-substituted five-membered heteroaromatics have attracted great interest over the past years due to their presence in a large number of pharmaceuticals and natural products. Recently, an advance in the preparation of these scaffolds was achieved by employing a C-H functionalization strategy. This method allows easy access to these biaryl motifs by precluding the necessity of preparing specific coupling partners, although poor regioselectivity is sometimes observed when more than one reactive C-H is present on the substrate. In an effort to circumvent this liability, we envisioned the use of a carboxylic acid moiety as a blocking group that could be later functionalized or removed. Remarkably, the coupling was found to occur exclusively at the position previously occupied by the acid, even in the presence of a reactive C-H group. This selective transformation was also found to proceed with other heteroaromatic carboxylic acids, allowing for the preparation of a variety of aryl-substituted heteroaromatics that would be difficult to obtain via other methods.
