Synthesis and X-ray crystal structure of a difunctionalized pillar[5]arene at A1/B2 positions by in situcyclization and deprotection

Abstract

The reaction of 1,4-dimethoxybenzene and paraformaldehyde using AlBr3 yields multiple-deprotected pillar[5]arenes. A1/B2 di-deprotected pillar[5]arene can be isolated by silica gel chromatography and washing procedures. The X-ray structure and polymerization of the A1/B2 di-deprotected pillar[5]arene are reported.
