trans-1,2-Bis(4-pyridyl)ethylene Use and Manufacturing

Methods of Manufacturing

400μL (4.12mmol) of 4-picoline reacted with 3.0mL (4.32mmol) of LDA in THF (5mL) at −70°C. In the absence of light, 465mL (4.12mmol) of 4-piridincarboxyaldehyde was dropwise added with continuous stirring. After 24h of reflux in the presence of 10mL of acetic acid, the reaction mixture led to a yellow solution, from which a pale-yellow solid was separated by rotatory evaporation. The solid was purified employing column chromatography in analogous conditions to the ones previously mentioned (368mg, 49percent).
