The electrochem. in-situ oxidative sulfonylation of phenols with sulfinic acids access to sulfonylated hydroquinones has been developed. A series of sulfonylated hydroquinones were prepared under mild mediator-, catalyst- and exogenous-oxidant-free conditions. Notably, such an electrochem. in-situ-oxidative synthetic strategy presented wide functional group tolerance and amenability to gram-scale synthesis with 62-80% yields. This study involved multiple reactions and reactants, such as 4-Benzyloxyphenol (cas: 103-16-2Category: ethers-buliding-blocks).
4-Benzyloxyphenol (cas: 103-16-2) belongs to ethers. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. Many esters have the potential for conformational isomerism, but they tend to adopt an s-cis (or Z) conformation rather than the s-trans (or E) alternative, due to a combination of hyperconjugation and dipole minimization effects. The preference for the Z conformation is influenced by the nature of the substituents and solvent, if present. Lactones with small rings are restricted to the s-trans (i.e. E) conformation due to their cyclic structure.Category: ethers-buliding-blocks
