2,3,3',4'-BiphenyLtetracarboxylic is using NiF2-PPh_3(PPh_3: triphenylphosphine) as the catalytic system, the cross-coupling reaction of 4-bromodimethylphenylg reagent and 3-chloro-xylene was efficiently achieved and 2,3 was synthesized., 3 '4'-tetramethyl benzene(3,4 '-TMDP), the latter prepared 3,4'-BPDA by liquid phase oxidation and high temperature dehydration to anhydride, with a two-step total yield of 74 %. Compared with the preparation of 3,4 '-BPDA from dimethyl phthalate or mixed dimethyl phthalate, this route does not involve the hydrolysis of esters and the separation of isomers, so separation and environmental protection have Very obvious advantages, while the synthesis route is simpler.
2,3,3',4'-BiphenyLtetracarboxylic is also named as α-BPDA;(4,5'-Biisobenzofuran)-1,1',3,3'-tetrone.
2,3,3',4'-BiphenyLtetracarboxylic has been supplying from UCHEM in large quantity with competitive price.
