Conclusions
-
1.
Some N-substituted 2-mercapto-3-thenylidenimines were synthesized, which contain the dimethylaminomethyl group in the 5 position of the thiophene ring, and also some chelates based on them.
-
2.
The dimethylamino group is attacked and the chelate ring is retained when the 5-dimethylaminomethyl-substituted chelates of mercaptoa Idimines belonging to the thiophene series are treated with CH3I in chloroform solution.
