Abstract: NEW MATERIAL:The pyrrole compound of formula (R is higher alkyl). EXAMPLE:3-Octylpyrrole. USE:The polymer of the compound is useful as an organic conductive polymer. PREPARATION:The objective compound of formula can be produced by acylating N-sulfonated pyrrole with a carboxylic acid chloride in the presence of a Friedel-Crafts catalyst, desulfonating the reaction product, separating an alkyl-3-pyrrolyl ketone from the obtained mixture of 2-substituted pyrrole and 3-substituted pyrrole and purifying and reducing the separated ketone. The Friedel-Crafts catalyst is e.g., stannic chloride or aluminum chloride and the reducing agent is aluminum lithium hydride, etc.
