R. Ostaszewski et al., INFLUENCE OF BASE AND SOLVENT ON THE REACTION BETWEEN P-CRESOL AND FORMALDEHYDE LEADING TO P-METHYLCALIX[N]ARENES, Polish Journal of Chemistry, 71(8), 1997, pp. 1053-1059
Effects of solvent and base on the reaction of p-cresol with formaldeh
yde were studied using a liquid SIMS method. In all cases, complex mix
tures of p-methylcalix[n]arenes were obtained and selectivities depend
ed on the cation type and solvent used. Two pure products, p-methylcal
ix [7]arene and p-methylcalix [8]arene, were isolated.
