Rh(I)-catalyzed decarbonylative direct C-H bond vinylation and dienylation of arenes with readily available acrylic acid and (E)-penta-2,4-dienoic acid under chelation assistance were developed for the first time. A significant effect of the ligand on the reactivity was observed with the bidentate phosphine ligand being optimal. This protocol was efficient under oxidant-free conditions to access synthetically valuable styrenes and 1-aryl-1,3-butadienes in high yields with a broad substrate scope and good functionality tolerance. In the experiment, the researchers used many compounds, for example, 2-(m-Tolyl)pyridine (cas: 4373-61-9Formula: C12H11N).
2-(m-Tolyl)pyridine (cas: 4373-61-9) belongs to pyridine derivatives. Pyridines are an important class of heterocycles and occur in polysubstituted forms in many naturally occurring biologically active compounds, drug molecules and chiral ligands. 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.Formula: C12H11N
