Lui, Yuen Wai published the artcileMethylation with Dimethyl Carbonate/Dimethyl Sulfide Mixtures: An Integrated Process without Addition of Acid/Base and Formation of Residual Salts, HPLC of Formula: 151-10-0, the main research area is methylphenol preparation; methylbenzoate preparation; phenylpropanenitrile preparation; alkylation; dimethyl carbonate; green solvent; lignin; organocatalysis.
Di-Me sulfide, a major byproduct of the Kraft pulping process, was used as an inexpensive and sustainable catalyst/co-reagent (Me donor) for various methylations with di-Me carbonate (as both reagent and solvent), which afforded excellent yields of O-methylated phenols and benzoic acids, and mono-C-methylated arylacetonitriles. Furthermore, these products could be isolated using a remarkably straightforward workup and purification procedure, realized by di-Me sulfide’s neutral and distillable nature and the absence of residual salts. The likely mechanisms of these methylations were elucidated using exptl. and theor. methods, which revealed that the key step involves the generation of a highly reactive trimethylsulfonium methylcarbonate intermediate. The phenol methylation process represents a rare example of a Williamson-type reaction that occurs without the addition of a Bronsted base.
