In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Asymmetric Propargylic Radical Cyanation Enabled by Dual Organophotoredox and Copper Catalysis, published in 2019-04-17, which mentions a compound: 15418-29-8, mainly applied to asym propargylic radical cyanation dual organophotoredox copper catalysis, Synthetic Route of C8H12BCuF4N4.
The first asym. propargylic radical cyanation was realized through a dual photoredox and copper catalysis. An organic photocatalyst serves to both generate propargyl radicals and oxidize Cu(I) species to Cu(II) species. A chiral Cu complex functions as an efficient organometallic catalyst to reassemble the propargyl radical and cyanide in an enantio-controlled manner. Thus, a diverse range of optically active propargyl cyanides were produced with high reaction efficiency and enantioselectivities (28 examples, 57-97% yields and 83-98% ee). Moreover, mechanistic investigations including experiments and d. functional theory calculations were performed to illustrate the reaction pathway and stereochem. results. Thus, e.g., propargyl substrate I + TMSCN → II (90%, 91% ee) in presence of Cu(MeCN)4BF4, a chiral bis-oxazoline ligand and 10-phenyl-10H-phenothiazine as the organic photocatalyst.
Here is just a brief introduction to this compound(15418-29-8)Synthetic Route of C8H12BCuF4N4, more information about the compound(Copper(I) tetra(acetonitrile) tetrafluoroborate) is in the article, you can click the link below.
