Cross couplings between simple allylic alcs. and aryl and vinyl boronic acids are efficiently catalyzed by nickel(0) catalysts and bidentate N-heterocyclic carbene/phosphine ligands. The bidentate nature of the ligand is shown to extend catalyst lifetime and enable high yields of the corresponding cross-coupling products. X-ray crystallog. confirms the bidentate nature of the ligand scaffold. Multistep cross coupling-alkene/alkyne insertions reactions are also conducted and the bidentate nature of the substrate makes the pendant phosphine of the ligand unnecessary. This study involved multiple reactions and reactants, such as 2-(3-Methoxyphenyl)-5,5-dimethyl-1,3,2-dioxaborinane (cas: 1003858-50-1Category: ethers-buliding-blocks).
2-(3-Methoxyphenyl)-5,5-dimethyl-1,3,2-dioxaborinane (cas: 1003858-50-1) belongs to ethers. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. Acyl chlorides and acid anhydrides alcoholysis is another way to produce esters. Acyl chlorides and acid anhydrides react with alcohols to produce esters. Anydrous conditions are recommended since both acyl chlorides and acid anhydrides react with water.Category: ethers-buliding-blocks
