Hydrochloric Acid → 4,4'-(Ethene-1,1-diyl)bis(N,N-diethylaniline)

Participants

Reaction Steps

Into 200 ml of IN--HCl solution was dissolved 10 g of 2,2-bis(4-diethylaminophenyl)propionic acid. Thereto was gradually added 5.7 g of ferric chloride at room temperature and the mixture was reacted with stirring for 2 hours. The reaction mixture was adjusted to alkaline with addition of aqueous solution of sodium hydroxide and then extracted with 50 ml of toluene. The toluene layer was concentrated at a reduced pressure to obtain crystals. The crystal was recrystallized from ethanol to give 6.5 g (yield 74.3%) of 1,1-bis(4-diethylaminophenyl)ethylene, having a melting point of 100°~102° C.
