New electrically conductive material suitable particularly for a secondary battery and a process for preparing the electrically conductive material are provided. The process for the preparation of the electrically conductive material comprises the steps of reacting a compound having conjugated double bonds with an oxidizing agent wherein the oxidizing agent comprises a cupric compound and a nitrile compound. The electrically conductive material comprises grainy polypyrrole obtained by reacting a pyrrole compound with an oxidizing agent which is constituted by primary particles having an average particle size of 0.01 to 0.4 µm and has a press molding density of 1 to 1.6 g/cm³.

We have found that N,N-dimethylethanolamine (deanol) is a useful solvent and ligand for copper catalyzed amination of a variety of unactivated and activated 2- or 3-halothiophenes. Primary amines, acyclic secondary amines, cyclic secondary amines and acyclic secondary amines with 2-hydroxyethyl functionality react with halothiophenes in moderate to excellent yields. The mildly basic conditions utilized are compatible with many functional groups. The animation of halobithiophenes has also been examined. The aminothiophenes produced by this method are important intermediates in a variety of electronic and optoelectronic materials. (C) 2004 Elsevier Ltd. All rights reserved.
