Abstract: The structures of a series of bis (trimethylsily1) amides have been investigated by nmr and ir spectroscopy. A study of the ljN derivative of bis (trimethylsily1) formamide provides definitive evidence for the amide structure and the free energy of activation for the rotational process is found to be 11.6 kcal,/mol. The structures of the other amides were determined from their nmr characteristics, and all were found to have the imidate structure. ...
