Author(s): Urbain C. Kassehin*, Diels-Alder cyclo-addition between anthracene-9-methanol and maleimide in water was selected as benchmark reaction and demonstrated how water as a Jul 16, 2013 A diene (9-anthracenemethanol) and a dienophile (N-methylmaleimide) are refluxed in water for 1 hour to afford the Diels-Alder cylcoadduct. In this experiment, anthracene-9-methanol and N-methylmaleimide were reacted in. solution to produce a single organic product, · N-methylmaleimide, the DMF. I2 Complex as Efficient Green Catalyst in the Diels-alder Reaction of Anthracene-9-Methanol with Maleimide. Place 0.065q of finely pulverized 9-anthracenemethanol and 50 mL of water in a 100-mL round-bottomed flask equipped with a magnetic.stir bar.

To this stirred solution, a 2-butanone (7 mL) solution of potassium hydroxide (KOH, 5.6 g, 0.1 mol) and potassium iodide (KI, 16.7g, 0.1 mmol) was added as solids at ambient temperature. Diels-Alder Reaction of Anthracene-9-Methanol with N-Methylmaleimide. Results In this experiment, anthracene-9-methanol and N-methylmaleimide were reacted in solution to produce a single organic product, anthracene-maleic anhydride Diels-Alder adduct, in crystal form. CAS: 1468-95-7 MDL: MFCD00001264 Synonyms: Anthracene-9-methanol , 9-Anthrylmethanol Results: Based on Pearson's SHAB (Soft and Hard Acids and Bases) theory, we have first established that the Diels-Alder cyclo-addition of our benchmark reaction (anthracene-9-methanol and maleimide) is a process submitted to generalized acid-base catalysis and in a second step we have developed within the context of the Green Chemistry an original efficient catalyst i.e. the DMF.I2 complex 2004-03-15 · Trial Diels–Alder reactions were performed by heating oxazoline 2 in toluene at reflux for 2 h with maleic anhydride and N-methylmaleimide.Surprisingly, no reaction was observed with maleic anhydride, however some product (73%) was observed with N-methyl maleimide giving the addition adduct as a 50:50 mixture of diastereoisomers 9 and 10 as observed from the signals in the 1 H NMR spectrum (). Results: Based on Pearson's SHAB (Soft and Hard Acids and Bases) theory, we have first established that the Diels-Alder cyclo-addition of our benchmark reaction (anthracene-9-methanol and maleimide) is a process submitted to generalized acid-base catalysis and in a second step we have developed within the context of the Green Chemistry an original efficient catalyst i.e. the DMF.I2 complex Anthracene definition, a colorless, crystalline powder, C14H12, obtained from coal tar and having a violet fluorescence: used chiefly as a source of anthraquinone and alizarin, and in the process of measuring radioactive materials.
