New discoveries in chemical research and development in 2021. As an important bridge between the micro, chemistry is one of the main methods and means for humans to understand and transform the material world. In an article, author is Mao, Wenbin, once mentioned the application of 120-21-8, Electric Literature of 120-21-8, category is benzoxazole. Now introduce a scientific discovery about this category.
A new application of silicon Grignard reagents in C(sp(3))-Si bond formation is reported. With the aid of BF3 center dot OEt2, these silicon nucleophiles add across alkenes activated by various azaaryl groups under copper catalysis. An enantioselective version employing benzoxazole-activated alkenes as substrates and a CuI-josiphos complex as catalyst has been developed, forming the C(sp3)-Si bond with good to high enantiomeric ratios (up to 97:3). The method expands the toolbox for conjugate addition type C(sp(3))-Si bond formation.
Electric Literature of 120-21-8, Consequently, the presence of a catalyst will permit a system to reach equilibrium more quickly, but it has no effect on the position of the equilibrium as reflected in the value of its equilibrium constant.I hope my blog about 120-21-8 is helpful to your research.
