Research on Synthesis Procedures for Intermediates Required for High Temperature Stable Polymeric Materials
Abstract
Work on the synthesis of the following substances is reported: Benzidine 3,3'-dicarboxylic acid, 6,6'-bis-((4H),3,1-benzoxazine-2,4-(1H)dione), diethyl 2,5-diaminoterephthalate, pentafluorophenylphosphonous dibromide, bis(pentafluorophenyl)-phosphinous bromide, perfluoro-1-bromo-4-n-octylbenzene, 1,1'bis(formyl)ferrocene, 1,3-bis(phenylglyoxaloyl) benzene, pyracyloquinone, and p,p'-oxydibenzil. Work on the characterization of the following compounds is reported: 1,1'-bis(formyl)ferrocene, ruthenocene, hexabromobenzene and hydroxymethylferrocene. The purification of 1,4,5,8-naphthalenetetracarboxylic acid and 1,4,5,8-naphthalenetetracarboxylic 1:8,4:5-dianhydride, and the preparation of poly((7-oxo-7H,10H-benz(de)-imidazo(4',5':5,6)benzimidazo(2, 1-a) isoquinoline-3,4:10,11-tetrayl)-10-carbonyl) (BBL polymer) is also reported.
