One of the shortest and most efficient routes toward a series of functionalized pentahelicenes is reported. Benzylic (dibromo)methine coupling is an important entry into functional helicene chem. It allowed a mono- or a double functionalization by some metal-catalyzed Ar-C, Ar-S, Ar-CN, and Ar-I bond formations. Those functions offer new avenues for further applications. For instance, helicene (I) can be supported on a Ag(001) surface, which was characterized by high-resolution NC-AFM imaging. In the experiment, the researchers used many compounds, for example, Sodium 2-methyl-2-propanethiolate (cas: 29364-29-2Recommanded Product: 29364-29-2).
Sodium 2-methyl-2-propanethiolate (cas: 29364-29-2) belongs to alcohols. The oxygen atom of the strongly polarized O―H bond of an alcohol pulls electron density away from the hydrogen atom. This polarized hydrogen, which bears a partial positive charge, can form a hydrogen bond with a pair of nonbonding electrons on another oxygen atom. Grignard and organolithium reagents are powerful tools for organic synthesis, and the most common products of their reactions are alcohols.Recommanded Product: 29364-29-2
