  N,N′-Dicyano-p-acepleiadylenequinonediimine (DCNAPQ-DI) and its 1,2-dibromo derivative (Br2-DCNAPQDI), a new family of acepleiadylene-based DCNQI type electron acceptors have been synthesized. Br2-DCNAPQDI exhibiting the first half-wave reduction potential of −0.03 V vs SCE afforded a fairly high conducting Cu salt.

• NOVEL PROCESS FOR THE PREPARATION OF CYCLIC PERI-SUCCINOYLACENAPHTHENE AND RELATED 1,4-DIKETO COMPOUNDS

  The present invention relates to a novel process for the synthesis of cyclic perisuccinoylacenaphthene and related 1,4-diketo compounds, especially 3,4,8,9-tetrahrdrocyclohepta[fg]acenaphthylene-7,10-dione (Ia). It is the single step process in which acenaphthene is converted into 3,4,8,9- tetrahydrocyclohepta[fg]acenaphthylene-7, 10-dione using Lewis acid in better yield. This method eliminates the purification of intermediates involved in the synthesis and reduces the use of stringent requirements of metal catalyst and solvents. The invention further relates to their uses especially for synthesis of various pigments, dyes for high end applications, and also various intermediates for drugs or pharmaceutically active composition/ intermediates.

  本发明涉及一种合成环过琥珀酰基苊和相关 1,4- 二酮化合物，特别是 3,4,8,9- 四氢环庚二烯并[fg]苊-7,10-二酮 (Ia) 的新工艺。这是一种利用路易斯酸将苊转化为 3,4,8,9-四氢环庚烷并[fg]苊-7,10-二酮的单步工艺，收率较高。这种方法省去了合成过程中中间产物的纯化，减少了对金属催化剂和溶剂的严格要求。本发明还涉及它们的用途，特别是用于合成各种颜料、高端应用染料以及各种药物中间体或药用活性成分/中间体。
