Abstract

INTRODUCTION β-Quinolinyl sulfides of types 1-6 (n= 0) were previously subjected to reaction with nitrating mixture. In all instances it led primarily to the formation of the respective β-quinolinyl sulfoxides 1-6 (n= 1)[1-7]. Under further treatment with nitrating mixture (0-5 C) some of them (2-6, n= 1) underwent nitration at the 6quinolinyl, 8quinolinyl [1, 3] and even 5quinolinyl positions [4], but 4-alkylthio derivatives of type 4 (X= SR) and 3 ...
