Reference of 250285-32-6, Chemistry can be defined as the study of matter and the changes it undergoes. You¡¯ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology.250285-32-6, Name is 1,3-Bis(2,6-diisopropylphenyl)imidazolium chloride, molecular formula is C27H37ClN2. In a patent, introducing its new discovery.
Three nuclear nitrogen heterocyclic cabeen arrowhead compound and synthetic method and application (by machine translation)
The present invention has offered a kind of three nuclear nitrogen heterocyclic cabeen arrowhead compounds and synthesis method and catalytic Suzuki coupling reaction in the application, the organic compound synthesis field. The compound of the general formula as follows: In the above formula R is 2, 6 – diisopropyl or 2, 4, 6 – trimethyl; R1 For isopropyl or benzyl; X chlorine, bromine atom. The invention consists of a nitrogen-containing heterocyclic compound, cabeen salt, palladium source materials such as the one-step reaction to synthesize a series of three nuclear nitrogen heterocyclic cabeen arrowhead compound, operation is simple and easy, and the yield is high, provides a synthesis of the three nuclear nitrogen heterocyclic compound cabeen arrowhead new ways. Compounds of the invention are C – C key construction provides a novel metal catalyst, used for catalyzing the chlorinated aromatic hydrocarbon aryl boric acid with the Suzuki coupling reaction, less catalyst levels, the use of inexpensive and easily obtained alkali, the reaction solvent is water, the catalytic effect is better.
