Tm. Jyothi et al., Selective methylation of phenol, aniline and catechol with dimethyl carbonate over calcined Mg-Al hydrotalcites, SYN COMMUN, 30(21), 2000, pp. 3929-3934
Calcined Mg-Al hydrotalcites (Mg/Al = 3) can be used as an efficient cataly
st in the selective O-methylation of phenol and catechol and N-monomethylat
ion of aniline employing dimethylcarbonate (DMC) as a methylating agent in
vapor phase at 275 degrees C.
