摘要

Silylarsines have been used to synthesize arsinogallanes Dynamic NMR spectroscopy studies of one of these, (Me3SiCH2)2As)2GaC1)2, show it has novel fluxional properties. Changes of the 1H and 13C NMR spectra were reconciled by rapid exchange of the endo- and exocyclic bis(trimethylsilylmethyl)arsino groups, and spectra simulated on this basis were in excellent agreement with the experimental data. A thermal conductivity (Delta G) of 17.0 + or - 0.0 kcal/mol for the 13C exchange was obtained by line shape analysis, and was in agreement with the estimate derived from the coalescence temperature. The 1H exchange process between 22 and 57 C could be simulated using the same kinetic parameters, without invoking pyramidal inversion of the exocyclic arsenics.
