Wang, Xuri published the artcileHollow, mesoporous, eutectic Zn1-xMgxO nano-spheres as solid acid-base catalysts for the highly regio-selective O-methylation of 1,2-diphenols, Computed Properties of 151-10-0, the main research area is magnesium zinc oxide methylation regioselective catalyst nanosphere composite kinetics.
The highly regio-selective O-methylation of catechol with di-Me carbonate (DMC), catalyzed by a solid acid-base catalyst, is an environmentally friendly chem. process for industrial production of guaiacol. However, a guaiacol yield below 84% and high reaction temperature above 280 °C limit its industrial application. Here, hollow, mesoporous Zn1-xMgxO nano-spheres with a eutectic structure, denoted as Zn1-xMgxO HMNSs (x = 0.012-0.089), are facilely fabricated via the calcination of Mg2+/Zn2+ ion-adsorbing carbon spheres at 500 °C in air. In the O-methylation of catechol with DMC at 180 °C, Zn1-xMgxO HMNSs (x = 0.052) afford guaiacol in 95.5% yield with a complete catechol conversion. Furthermore, 89.0-95.3% mono-ether yields with high 1,2-diphenol conversions (94.5-100%) are also obtained for the other 1,2-diphenols bearing -CH3 and -Br groups. Moreover, a plausible mechanism for highly selective O-methylation of catechol with DMC is proposed, in which the single-site activation and double-site activation of phenolic hydroxyls by the basic oxygen of Mg-O afford guaiacol and veratrole, resp.
