Paragraph 0047; 0048, (2017/05/26)
The invention provides a 2 - alkyl anthraquinone synthetic method, the 2 - alkyl anthraquinone synthetic method comprises the following steps: the 2 - (4' - alkyl benzoyl) benzoic acid in the presence of a solvent through the acyl acyl; under the action of the promoter, using anhydrous aluminum ring to carry out the dehydrochlorination; reactant through hydrolysis, liquid separation, pressure reducing desolventizing, drying, to obtain 2 - alkyl anthraquinone. The beneficial effect of the present invention is: not the use of fuming sulfuric acid, mild reaction conditions, acid-free, simple process operation, the product quality is stable, and the yield of the product than the existing production process to improve the 5 - 10%.

2-Benzoylbenzoyl azides undergo facile cyclization under acidic conditions to give substituted dibenzo[b,f][1,5]-diazocines in good yields. This approach shortens the synthetic steps toward these compounds as compared with conventional methods. The mechanism of the diazocine synthesis is assumed to proceed by an unprecedented intermolecular [2 + 2] cyclization.

, p. 9473 - 9476 (2007/10/03)
A new polymer based on a functionalized benzofulvene moiety has been synthesized by spontaneous polymerization of the monomer in the solid state. This polymer shows a very high molar mass, high solubility in the most common organic solvents, and thermorev
UNE SYNTHESE ORIGINALE ET INATTENDUE D'ISOCOUMARINES FONCTIONNELLES
Babin, P.,Dunogues, J.
, p. 4389 - 4392 (2007/10/02)
Reaction of Ph3P=CH-COOEt with ortho benzoyl benzoic acid derivates offers an easy and surprising entry to functional isocoumarins via the thermal decomposition of the keto-ylide intermediates or by subsequent oxidation of the expected indenones.
