Investigation of the structure and thermolysis of quaternary salts of 2-alkyl- and 2-arylamino derivatives of thiazolines

Article abstract of DOI:10.1007/BF00506033

2-Arylamino derivatives of 5-methylthiazoline react with alkyl iodides to give quaternary salts with primarily an exocyclic orientation of the C=N bond, while the C=N bond is localized in the: ring in the corresponding salts of 2-alkylamino derivatives of thiazoline. The decomposition of these salts leads to the corresponding 2-arylaminothiazolidines and 2-alkylaminothiazolines.
