METHOD OF PRODUCING 3-ALKYL-2-(2-THIENYL)PYRROLES AND N-VINYL DERIVATIVES THEREOF Russian patent published in 2013 - IPC C07D409/04 

FIELD: chemistry.

SUBSTANCE: invention relates to organic synthesis and specifically to a method of producing 2-(2-thienyl)-3-alkyl pyrroles and N-vinyl derivatives thereof of general formula and , where Alk denotes any linear alkyl substitute. The method is a single-reactor three-component reaction of 2-acylthiophene, hydroxylamine chloride and excess acetylene in the presence of an alkali metal hydroxide with adding sodium bicarbonate to DMSO in an autoclave under acetylene pressure for 1-3 hours at temperature of 80-120°C in a wide range of molar concentration of reactants; molar ratio of reactants acylthiophene: hydroxylamine chloride: acetylene: MOH: DMSO varies in the range of 1:1.0-1.5:2-25:1.5-2.5:30-50.

EFFECT: method of obtaining novel compounds which can be used as monomers for producing electroconductive polymers, particularly as active components of electrodes of polymer rechargeable batteries and electrochromic devices.
