Abstract
^1^H‐(^119^Sn) double resonance experiments show that tin shielding in cyclic organotin‐alkane‐α, ω‐dithiolates and in 1,1‐diorganostannacycloalkanes is sensitive to ring size. A shift to low field arises when the interbond angles at tin are abnormally small, and there are accompanying changes in the Lewis acid strength of the tin atom.
