Role of polar solvents for the synthesis of pillar[6]arenes

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 H 2 SO 4 or BF 3 ·OEt 2 in polar solvent media (acetonitrile, ethyl alcohol, acetone etc. ). I...

Summary: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 H 2 SO 4 or BF 3 ·OEt 2 in polar solvent media (acetonitrile, ethyl alcohol, acetone etc. ). In all cases the interaction afforded pillar[6]arenes in high yields.
