3-Chloro-3-(1H,1H-pentadecafluorooctoxy)diazirine (7a) and 3,3-bis(1H,
1H-pentadecafluorooctoxy)diazirine (8) have been prepared via several
steps from 1H,1H-pentadecafluorooctanol (3). Photolysis or thermolysis
of these diazirines generated the corresponding carbenes (1 or 2), wh
ich underwent intermolecular reactions with HCl, alcohol 3 and acrylon
itrile.
