1,1-Bis(trifluoromethyl)-substituted alkenes 6 are obtained by the reaction of aldehydes 5 with triphenylphosphine (4) and 2, 2-dichlorohexafluoropropane (3) in modest to good yields. The alkenes 6 are not easily accessible by other routes.
1,1-双(三
氟甲基)取代烯烃6是通过醛5与
三苯基膦(4)及2,2-二
氯六氟丙烷(3)反应获得的,产率中等到良好。这些烯烃6通过其他途径不易获得。
