A new porous organic polymer containing Tr?ger's base units: Evaluation of the catalytic activity in Knoevenagel condensation reaction

The classic Tr?ger's base polymerization of a diamine and dimethoxymethane with trifluoroacetic acid as catalyst generated a Tr?ger's base-type polymer (TBP), which exhibited the absolute insolubility in a variety of organic solvents because of its highly aggregated model. A new porous organic polymer was obtained by a simple Tr?ger's base polymerization reaction between a diamine and formaldehyde in the form of acetal in the presence of trifluoroacetic acid as catalyst. Tr?ger's base-type polymer (TBP) resulted insoluble in a wide range of organic solvents due to its rigid and aromatic structure. TBP was characterized spectroscopically (FT-IR), thermally and morphologically. As result, a thermostable and amorphous polymer bearing pores ranging between 50 and 300 nm and macro-voids of up to 12 μm was obtained. Due to the insolubility of the TBP, it was tested as a metal-free heterogeneous catalyst in the Knoevenagel condensation reaction, showing a high efficiency. For this, the optimal catalyst load, reaction time and reuse of the catalyst were studied using benzaldehyde and malononitrile as substrates. Furthermore, aldehydes with variable chain sizes and ethyl cyanoacetate replacing malononitrile were tested as substrate with a high percent of conversion (97–99%).

SPIROCYCLIC MEISENHEIMER COMPLEXES XVI. EFFECT OF THE NITRO GROUP AS A SUBSTITUENT IN THE PYROCATECHOL UNIT ON THE CYCLIZATION OF POLYNITROPHENYL ETHERS OF PYROCATECHOL TO DIPHENYLENE DIOXIDES

As a result of the reversible Smiles rearrangement the intramolecular cyclization of 2-picryloxy-4-nitrophenol leads to the formation of two regioisomeric 1,3,7- and 1,3,8-trinitrodiphenylene dioxides in a ratio of 1 : 2, whereas only one unrearranged 1,3,6-trinitrodiphenylene dioxide is formed from 2-picryloxy-6-nitrophenol.The cyclization of 2-(2,4-dinitrophenoxy)-4-nitrophenol takes place with significantly greater difficulty and leads to the rearranged 2,8-dinitrodiphenylene dioxide.Trinitrocyclohexadienide spiro complexes with 4-nitro-, 5-nitro-, and 5,6-dichlorobenzodioxolane rings were fixed and isolated in the form of triethylammonium salts.
