Hexafluoroacetone azine reacts with ethylene, with propene, and with but-1-ene at 160—180° to give high yields of the corresponding 1 : 2 adducts, 1,5-diazabicyclo[3,3,0]octanes. Acetylene reacts similarly to give the corresponding 1,5-diazabicyclo[3,3,0]octa-2,6-diene. The olefins also react under photochemical conditions to give the same products, but acetylene does not react. The azine does not react
六氟丙酮嗪与乙烯,丙烯和丁-1-烯在160-180°下反应,得到高产率的相应的1:2-加合物1,5-二氮杂双环[3,3,0]辛烷。乙炔类似地反应,得到相应的1,5-二氮杂双环[3,3,0]八-2,6-二烯。烯烃还在光化学条件下反应,得到相同的产物,但乙炔不反应。在相当的条件下,该嗪不会与缺电子的烯烃或乙炔反应。乙烯或丙烯加合物的热解以高收率得到3,3,3-三氟-2-三氟甲基丙烯; 乙炔加合物主要得到六氟乙烷和3,3,3-三氟丙炔与1,1,1,6,6,6,6-六氟-2,5-双三氟甲基六-2-,4-二烯的混合物。
