Description
Technical field
The invention belongs to organic chemical synthesis technical field more particularly to a kind of fluoro- 3- aromatic substituted acrylic acid methyl esters chemical combination of 2-
Object and the preparation method and application thereof.
Background technique
Fluorochemical has a wide range of applications in the synthesis of natural products and drug.In recent decades, fluorine-containing chemical combination
Object is especially the synthesis of fluorine-containing carboxylic acid compound by the extensive concern of scientists and has made great progress, but still
There is complex steps, the disadvantages of raw material is not easy to obtain, and obtained based on the carboxylation reaction that the compound with fluoro-containing group carries out
The product structure arrived is also relatively simple.The reactive intermediate generated using multi-fluorinated compounds cheap and easy to get through carbon-fluorine bond fracture is straight
One kind can be provided more for the synthesis of fluorine-containing carboxylic acid compound by connecing the strategy for carrying out carboxylated with carbon dioxide gas precursor reactant
Direct and inexpensive approach.But due to the universal bond energy with higher of carbon-fluorine bond, it is broken that carry out carboxylated anti-by carbon-fluorine bond
Should it not developed well.Transition metal-catalyzed halogen (class halogen) is for hydrocarbon (including iodine, bromine, chlorine, triflate at present
Deng) although relatively common by carbon-halogen bond fracture and carbon dioxide reaction progress carboxylated, but similar method is but difficult to answer
For the carboxylated of carbon-fluorine bond, reason is that oxidation addition of the carbon-fluorine bond for transition-metal catalyst is difficult to carry out.
Grew up in recent years utilization can with light-exposed redox catalysis promote carbon-fluorine bond cleavage strategy can be effective
Realization multi-fluorinated compounds defluorinate functionalization.As document 1 (J.Xie, J.Yu, M.Rudolph, F.Rominger,
AndA.S.K.Hashmi, Angew.Chem.Int.Ed.2016,55,9416-9421) disclosed in method in, in illumination condition
The carbon-fluorine bond fracture of lower two fluoroolefins, forms alkenyl carbon radicals, and coupling directly occurs with the carbon radicals in system and obtains
Obtain the amine-methylated product of defluorinate.
Simultaneously, it is seen that light promote also have certain research within carboxylation reaction nearly 2 years, as document 2 (K.Shimomaki,
K.Murata, R.Martin, and N.Iwasawa, J.Am.Chem.Soc.2018,140,17338-17342) disclosed in side
In method, the strategy of use be using visible light redox catalysis mediate reduction system promote palladium chtalyst aryl halide (bromine,
Chlorine) for the carboxylation reaction of hydrocarbon, and then aryl carboxylic acid product.
In view of the multifunctionality of exploitation visible light redox catalysis, using in conjunction with photocatalysis and transition metal-catalyzed side
Method develops efficient multi-fluorinated compounds carbon-fluorine bond carboxylation reaction for carbon dioxide conversion and the preparation containing carboxylic acid fluoride all has
It is significant.
