Zimmer, Hans,Servay, Thomas K.
, p. 201 - 204 (2007/10/02)
Dianions derived from tetraphenyl arylene-bis--bis-phsphonates react with aromatic and heteroaromatic aldehydes to yield bis-acylated aromatics. Key words: α-Heterosubstituted phosphonate carbanions; diacylated heteroaromatics;
METHODS FOR SYNTHESIS OF AROMATIC BIS-1,2-DIKETONES, BISMETHOXYSTYRYLS, AND BISDEOXYBENZOINS FROM 1,4-DISTYRYLBENZENE

trans,trans-1,4-Distyrylbenzene was converted finally into 1,4-di(phenylglyoxaloyl)benzene by methoxybromination of the double bonds with N-bromosuccinimide in methanol, dehydrobromination, hydrolysis, and oxidation of the intermediate products.The methoxybromination is stereoselective but not regioselective.
Preparation of diketones

, (2008/06/13)
A method for preparing diketone starting materials useful in synthesizing tetraketone precursors for high temperature resistant polyquinoxaline resins. Dicarboxylic acid derivatives that contain no alpha hydrogens are contacted in the presence of a strong
