The invention discloses a preparation method of an N-arylpyrazole compound and an N-arylimidazole compound. The method comprises the following steps: reacting at 20-120 DEG C for 6-48 hours by taking aryl halide and pyrazole or imidazole as substrates and copper salt as a catalyst in an organic solvent in the presence of alkali and a nitrogenous ligand under nitrogen protection; and after the reaction is finished, separating and purifying a reaction liquid to obtain the N-arylpyrazole compound or the N-arylimidazole compound. A product prepared by utilizing the method disclosed by the invention can not only be directly used, but also be used for other reactions as a substrate and has the advantages of moderation in adopted reaction condition, simple operation step and post-processing process, high yield and suitability for large-scale production.

A simple and efficient Ci£N cross-coupling method of aryl halides with various heterocycles was reported, by using 10 mol% of CuI as catalyst and 1.2 equiv. NaH as base. Aryl iodides, aryl bromides and many substituted aryl chlorides could efficiently react with heterocycles, providing variety of N-arylated products in good to excellent yields. The ligand-free catalyst system was stable in air and could be readily reused. An efficient, convenient and applicable method was developed for the N-arylation of azaheterocycles catalyzed by CuI and NaH under ligand free condition. Copyright

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, 54109-03-4, name is 5-Chloroisobenzofuran-1(3H)-one, introducing its new discovery. Formula: C8H5ClO2

The combination of conventional transition-metal-catalyzed coupling (2 e? process) and photoredox catalysis (1 e? process) has emerged as a powerful approach to catalyze difficult cross-coupling reactions under mild reaction conditions. Reported is a palladium carbodicarbene (CDC) complex that mediates both a Suzuki?Miyaura coupling and photoredox catalysis for C?N bond formation upon visible-light irradiation. These two catalytic pathways can be combined to promote both conventional transition-metal-catalyzed coupling and photoredox catalysis to mediate C?H arylation under ambient conditions with a single catalyst in an efficient one-pot process.

A palladium-catalyzed pyrazole-directed regioselective oxidative C(sp2)-H functionalization of the N-phenyl ring in N-phenylpyrazoles to afford either a biaryl bis-pyrazole (via dehydrogenative homocoupling) or N-(o-hydroxyphenyl)pyrazole (via C-H oxygenation) or their mixture is described. The substitutions on the N-phenyl ring and the pyrazole ring and the dilution of the reaction medium with respect to the TFA/TFAA mixture (substrate concentration) have a remarkable influence on the outcome of the reaction. It was discovered that if the reactions were performed under highly dilute conditions (ca. 10 times) then N-(o-hydroxyphenyl)pyrazoles were the major or the sole products.

Carboxylation of 1-arylpyrazole derivatives was developed using a ruthenium-catalyzed ortho silylation in conjunction with fluoride-mediated carboxylation with carbon dioxide. The two nitrogen atoms of pyrazole play crucial roles in promoting ortho silylation via the formation of a five-membered ruthenacycle and in accelerating aryl anion formation by lowering the electron density of the aromatic ring.

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).

Palladium-catalyzed alkylations of sp2 and sp3 C-H bonds with either methylboroxine or alkylboronic acids were developed. Ag2O or AgCO3 is used as a crucial oxidant and promoter for the transmetalation step. Ether, ester, alcohol, and alkene functional groups are tolerated. A new C-H activation pathway differing from the cyclometalation process is elucidated using methylboroxine as the coupling partner. Copyright

Commercially available FeCl3·6H2O with conformationally rigid diamine ligand is a highly effective catalyst for N-arylation of pyrazoles using aryl and heteroaryl iodides. It is notable to show that this complex is tolerable under aqueous medium and particularly the whole reaction utilizes water as the sole solvent without any additional organic co-solvents and surfactants. Attempted study using other nitrogen nucleophiles is described. This newly developed system provides an alternative protocol to Cu- and Pd-catalyzed N-arylation reactions.

A general and efficient procedure for C?H alkenylation of arenes with a broad substrate scope catalyzed by Cp*CoIII was demonstrated with alkynes. A highly selective mono-alkenylation and sequential bis-C?H bond functionalization was displayed to exemplify the versatility of the cobalt catalyst. Isolation of cationic Cp*CoIII?alkenyl intermediate was achieved under identical catalytic conditions to further establish the proposed pathway.
