The reaction of bis(p-nitrophenoxy)-methane or p-nitrophenol with the excess paraformaldehyde under the pressence of concentrated sulfuric acid was investigated , and the benzodioxene derivative of methylene bridged oligomer of p-nitrophenol with two or three benzene nucoeus obtained. The four products were separated by chromatography, identified by IR, ^1H NMR, MS, respectively and three new compounds yielded. These compounds are used to Convergent stepwise synthesis of calixarene and long-chain methylene bridged oligomer.
