Abstract: A series of S-substituted N-methyl-6, 7-dihydro-SH-dibenzo [b, g][1, 5] thiazocinium salts (5a-e) have been prepared from the S-chloro derivative (5e), which was obtained from the corresponding sulfoxide (6) and thionyl chloride. An excellent linear relationship is observed between the'H and the I3C NMR chemical shifts of the N-methyl group and Hammett's um substituent constants at the sulfur. The structures of 5a-e have been shown ...
