Рубрики: ХИМИЧЕСКИЕ НАУКИ Кл.слова (ненормированные): HOST-GUEST COMPLEXATION -- WATER CHANNELS -- HIGH-YIELD SYNTHESIS Аннотация: An efficient procedure for the synthesis of pillar[6]arenes has been developed. The procedure involves the condensation of 1,4-dialkoxybenzenes and paraformaldehyde in the presence of a catalytic amount of H2SO4 or BF3 center dot OEt2 in polar solvent media (acetonitrile, ethyl alcohol, acetone etc.). In all cases the interaction afforded pillar[6]arenes in high yields. \\\\expert2\\nbo\\RSC Advances\\2015. Vol. 5, N 126. P. 104278-104282.pdf |
