| titleOfInvention | PROCEDURE FOR THE PRODUCTION OF BIPYRIDYLS. |
| abstract | Process for the production of bipyridyls, characterized in that it comprises reacting the corresponding substituted pyridines in the vapor phase with ammonia, said substituted pyridines being chosen between 2- (pyridyl) - and 4- (pyridyl) -tetrahydropyrans and tetrahydrothiopyranol, as well as among the substituted pyridines in which the substituent group is of structural formula -C (R) (R1) (R2), where R belongs to the group comprising hydrogen, halogens, hydroxyl, alkoxy and amino radicals; and R1 and R2 each represent a group of the general formula -CHn (XR3) 2-n CHm (XR4); in which X is chosen between sulfur and oxygen, n is from 0 to 2 and m is chosen from 1 to 2, R3 and R4 each belong to the group comprising hydrogen and alkyl, alkene, aryl, alkaryl, aralkyl and cycloaliphatic radicals .
