Tn. Vasilevskaya et al., METHYLATION OF PHENOL AND ITS DERIVATES WITH DIMETHYL SULFATE UNDER THE PHASE-TRANSFER CATALYSIS CONDITIONS, Sibirskij himiceskij zurnal, (1), 1993, pp. 37-40
A convenient metode has been developed for synthesis of methyl ethers
of phenol and its derivates by their reaktion with dimethyl sulfate un
der the phase transfer catalysis conditions in the presence of methylt
rialkylammonium methylsulfate and DB-18-k-6.
