## Abstract The analysis of the ^13^C NMR chemical shifts of 16 substituted 2‐phenylthiazolidines shows that the 1,3‐thiazolid‐2‐yl group exerts a deshielding effect at the __ipso__ carbon (C‐1′) and shielding effects at the __ortho__ and __para__ positions of the benzene ring (C‐2′ and C‐4′), and

There are many literature examples correlating C-13 n.m.r. substituent chemical shifts in substituted benzenes with Bsamett substituent constants.' The direction of these substituent chemical shifts has been logically explained in terms of substituent electronic properties; the electron donors resul
