Conclusions

  1. 1.

    When N-alkylallylamines are passed over alumina promoted by KOH (260–270°, space velocity 0.4 h−1), the double carbon—carbon bond is shifted from the terminal position toward the inside of the molecule. The yields of the main isomerization products — N-alkylpropenylamines — are 26–50%.

     
  2. 2.

    Under these conditions the double bond migrates still further with formation of N-propylidenealkylamines in yields of 10–15%.

     
  3. 3.

    Over the same catalyst at 260–310° the C=N bond migrates only in accordance with the scheme Ci=N-C2⇆C1- N=C2, and the isomerization C-N=C-C→C-N-C=C does not occur.
