An efficient and practical protocol for the Cr/Ni-catalyzed vinylation of aldehydes, based on the use of Mn/Cr alloy (ca. 10 % Cr) and TMSCl is reported. In the presence of NiCl2 (0.3 mol %) and 6,6′-diacetyl-2,2′-bipyridine bis(2,6-diisopropylphenyl)imine as an N4-chelating ligand (1 mol%), the vinylations proceed smoothly at room temperature The presence of catalytic amounts of MeOH and LiOAc as additives was found to further promote the efficiency of the catalytic system, even in the absence of the ligand. Detailed reaction monitoring revealed that LiOAc accelerates the product alc. silylation, thus increasing the turnover rate. In the experiment, the researchers used many compounds, for example, 2-Bromo-6-(2-methyl-1,3-dioxolan-2-yl)pyridine (cas: 49669-14-9Recommanded Product: 2-Bromo-6-(2-methyl-1,3-dioxolan-2-yl)pyridine).
2-Bromo-6-(2-methyl-1,3-dioxolan-2-yl)pyridine (cas: 49669-14-9) belongs to alcohols. Alcohols are among the most common organic compounds. They are used as sweeteners and in making perfumes, are valuable intermediates in the synthesis of other compounds, and are among the most abundantly produced organic chemicals in industry. Under carefully controlled conditions, simple alcohols can undergo intermolecular dehydration to give ethers. This reaction is effective only with methanol, ethanol, and other simple primary alcohols.Recommanded Product: 2-Bromo-6-(2-methyl-1,3-dioxolan-2-yl)pyridine
