A metal-free silyl-pyridylation of alkenes using silyl boronates and B2pin2 through a pyridine-mediated B-interelement activation was demonstrated, which provides a practical strategy for a variety of C4-silylalkylated pyridines. DFT calculations and control experiments show that the reaction proceeds through a silyl radical addition/radical-radical coupling sequence. This protocol features a broad substrate scope and excellent functional group compatibility, and thus it showcases great potential in the late-stage modification of bioactive mols. In the experiment, the researchers used many compounds, for example, 2-Fluoroisonicotinonitrile (cas: 3939-14-8Safety of 2-Fluoroisonicotinonitrile).
2-Fluoroisonicotinonitrile (cas: 3939-14-8) belongs to pyridine derivatives. Pyridine has a conjugated system of six π electrons that are delocalized over the ring. The molecule is planar and, thus, follows the Hückel criteria for aromatic systems. Several pyridine derivatives play important roles in biological systems. While its biosynthesis is not fully understood, nicotinic acid (vitamin B3) occurs in some bacteria, fungi, and mammals.Safety of 2-Fluoroisonicotinonitrile
