The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: Nickel(II) chloride ethylene glycol dimethyl ether complex( cas:29046-78-4 ) is researched.Formula: C4H10Cl2NiO2.Pieber, Bartholomaeus; Malik, Jamal A.; Cavedon, Cristian; Gisbertz, Sebastian; Savateev, Aleksandr; Cruz, Daniel; Heil, Tobias; Zhang, Guigang; Seeberger, Peter H. published the article 《Semi-heterogeneous Dual Nickel/Photocatalysis using Carbon Nitrides: Esterification of Carboxylic Acids with Aryl Halides》 about this compound( cas:29046-78-4 ) in Angewandte Chemie, International Edition. Keywords: graphitic carbon nitride nickel photocatalytic esterification catalyst; carboxylic acid aryl halide graphitic carbon nitride nickel esterification; aryl carboxylic ester preparation; dual catalysis; graphitic carbon nitride; heterogeneous catalysis; metallaphotoredox; photocatalysis. Let’s learn more about this compound (cas:29046-78-4).
Cross-coupling reactions mediated by dual nickel/photocatalysis are synthetically attractive but rely mainly on expensive, non-recyclable noble-metal complexes as photocatalysts. Heterogeneous semiconductors, which are commonly used for artificial photosynthesis and wastewater treatment, are a sustainable alternative. Graphitic carbon nitrides, a class of metal-free polymers that can be easily prepared from bulk chems., are heterogeneous semiconductors with high potential for photocatalytic organic transformations. Here, we demonstrate that graphitic carbon nitrides in combination with nickel catalysis can induce selective C-O cross-couplings of carboxylic acids with aryl halides, yielding the resp. aryl esters in excellent yield and selectivity. The heterogeneous organic photocatalyst exhibits a broad substrate scope, is able to harvest green light, and can be recycled multiple times. In situ FTIR was used to track the reaction progress to study this transformation at different irradiation wavelengths and reaction scales.
As far as I know, this compound(29046-78-4)Formula: C4H10Cl2NiO2 can be applied in many ways, which is helpful for the development of experiments. Therefore many people are doing relevant researches.
