Synthese von <i>N‐tert</i>‐Butyl‐4‐(<i>tert</i>‐butylimino)‐2‐penten‐2‐amin

Abstract

Synthesis of N‐tert ‐Butyl‐4‐( tert ‐butylimino)‐2‐penten‐2‐amine N‐tert ‐Butyl‐4‐( tert ‐butylimino)‐2‐penten‐2‐amine ( 5 ) has been prepared by stepwise exchange of oxygen in acetylacetone ( 1 ) by tert ‐butylamino groups followed by deprotonation. For the first step 1→2 either silylated 1 or 1 and an excess of Et 2 OBF 3 is required. The title compound 5 forms a single isomer in solution which is supposedly of the “U” type.
