18. The corresponding cross-peak between the α-proton of the iPr group and the α-carbon of the TMSM group was not observable due to coupling of the α-proton with the iPr methyl groups. Attempts to acquire a selectively decoupled HMBC spectrum failed to reveal the weak couplings across the zinc center.
19. Due to the chemical shift dependence on temperature, Δv changes as a function of temperature. Values for Δv at the coalescence temperatures were extrapolated for both the ethyl (1b) and isopropyl (1a) groups from low temperature chemical shift data. Since Δv is quite similar in the primary and secondary cases, the observed difference in fluxional behavior arises from a difference in chemical behavior.
