To provide a friction-reducing agent containing no sulfur nor phosphorus and being excellent in friction-reducing properties, and a lubricating oil composition using it. An alkanolamine represented by the following formula is used as a friction-reducing agent: wherein Aand Aare each independently a hydroxy group or a hydrogen atom, provided that Aand Aare not hydrogen atoms at the same time, Ris a hydrocarbon group having at most 30 carbon atoms, Rto Rare each independently a hydrogen atom or a hydrocarbon group having at most 30 carbon atoms, and m and n are each independently an integer of from 0 to 10.

Alkanolamine, friction-reducing agent, and lubricating oil composition

To provide a water-soluble polythiophene used as an electrically conductive material, and its production method. A polythiophene comprising at least one type of structural units selected from the group consisting of structural units represented by the formula (1), structural units represented by the formula (2), structural units represented by the formula (3), structural units represented by the formula (4), structural units represented by the formula (5) and structural units represented by the formula (6). The polythiophene is obtained by polymerizing at least one thiophene compound selected from the group consisting of a thiophene compound represented by the formula (15), a thiophene compound represented by the formula (16) and a thiophene compound represented by the formula (17) in water or an alcohol solvent in the presence of an oxidizing agent.

A catalyst composition for a cross-coupling reaction comprising a nickel salt-amine complex of formula (1), and triphenylphosphine. where Rthru Rindependently represent alkyl, aryl, heteroaryl or alkenyl; n is an integer of 1-6; and X independently represents halo, hydroxyl, nitrate or acetate group. Using the catalyst composition, a cross-coupling reaction is carried out between a boron-containing compound of formula (2) and a compound of formula (3). where Rand Rare the same as R-Rdefined above; Y independently represents hydroxyl or alkoxy, Z is halo, methanesulfonate or trifluoromethanesulfonate.
