In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Tandem Double-Cross-Coupling/Hydrothiolation Reaction of 2-Sulfenyl Benzimidazoles with Boronic Acids, published in 2019-08-02, which mentions a compound: 16400-32-1, Name is 1-Bromo-2-pentyne, Molecular C5H7Br, HPLC of Formula: 16400-32-1.
A new tandem palladium-catalyzed reaction involving a Suzuki-Miyaura coupling, a desulfenylative coupling, and a hydrothiolation of a triple bond is reported. Notably, the desulfenylative coupling occurs without copper(I) assistance and the hydrothiolation is totally regioselective and stereoselective. The overall process results in the double incorporation of the boronic acid and the reincorporation of the sulfenyl moiety into the product structure. Starting from 2-(bromobenzylsulfenyl)-1-propargyl benzimidazoles, the transformation led to variously substituted benzimidazoles bearing a stereodefined alkenyl sulfide.
Compound(16400-32-1)HPLC of Formula: 16400-32-1 received a lot of attention, and I have introduced some compounds in other articles, similar to this compound(1-Bromo-2-pentyne), if you are interested, you can check out my other related articles.
