标题:Thermal And Photochemical Rearrangements Of 3-Arylamino-2-Phenyl-1H-Inden-1-Ones To N-Arylphthalimides
摘要:Upon Heating To Above Their Melting Temperatures,3-Arylamino-2-Phenyl-1H-Inden-1-Ones And 2,2'-Diphenyl-3,3'-Bis(Arylimino)[2,2'-Biindan]-1,1'-Dione Undergo A Skeletal Rearrangement To Afford N-Arylphthalimides Along With Benzoic Acid In The Presence Of Atmospheric Oxygen. The Photoreaction Of These Compounds In Acetonitrile Also Results In The Formation Of These Products. The Mechanism Of The Reactions,Including The Formation Of A Peroxyl Radical Followed By Its Conversion To A Nitrogen-Centered Radical,Is Proposed.

标题:Synthesis of certain bis(phthalic anhydrides)

摘要:Monomeric high molecular weight dianhydrides or tetraacids can be produced by the nucleophilic coupling of a halo substituted phthalimides acid and an aliphatic or aromatic compound having polyfunctional groups capable of reacting with the halo moiety of the phthalinide followed by hydrolysis and dehydration. Specifically, 4-chlorophthalate sodium salt is converted to an imide to reduce side reactions with the carboxylic acid groups prior to reaction with 4,4'-disodiumdiphenylene oxide sulfone or 2,2-di (4-sodium phenoxide) propane. After the reaction of the imide and the sulfone or propane compounds, the diimide formed is converted to the corresponding dianhydride.
