4-halo-4-alkenal 2,3-dihalo- 1-alkene

The tri- and tetrahalides are in many cases readily available by dihalocarbene addition to the corresponding halo- or dihalo-alkene in other cases they may be obtained on a synthetically useful scale from carboxylic acids118 ... [Pg.1370]

There are no one-step syntheses of A(-alkylaziridines direct from alkenes of proven generality, the most thoroughly investigated being the reactions of iV-halo- and iV,iV-dihalo-alkylamines with alkenes referred to earlier (Scheme 6). They are probably radical reactions and are not stereospecific the A(-haloamine reagents are difficult to prepare cleanly, and are rather dangerous. Representative examples (6 of 17) prepared from halogenated alkylamines are listed in Scheme 14. [Pg.474]
