| Abstract: | The live-coordinate bicycloawstannowxides (1–6) in the presence of Et3N has been investigated by ♪1H NMR spectrograph. It has been found that the deuterium exrhange of αCH of five-coordinate bicycloazastannoxides with CD30D takes place, which is catalyzed by Et3N. In the presrnce of Et3 N(2 pL), the apparent rate constants (koba.) for the deuterium cxchangc in CD3OD) is determined by ♪1H NMR method, wd the value of kOba is in the range of (2.05-10.8) ×10-4 s-1. Thr effect of the substitutes on the rates and the kinetic mechanism are discussed. |
