Conclusions
-
1.
New aromatic amines with allyl-type substituents in the para position of the benzene ring were obtained as a result of the Claisen rearrangement in the reaction of secondary α-chloroalkenes with 2-methyl-6-ethylaniline and 2,5-xylidine.
-
2.
It was established that only the products of the ortho substitution are given from the cyclic a-chloroalkenes and 2,5-xylidine, whereby their formation was caused by the rearrangement of the corresponding N-alkenylamines which were obtained in the first stage.
-
3.
The para isomer of the 2,5-xylidine — 2,5-dimethyl-4-(2-chloro-1-methyl-2-butenyl)aniline — is formed in sequence as a result of the ortho-para migration of the allyl substituent.
