Are Ligand-Stabilized Carboxylic Acid Derivatives with GeTe Bonds Isolable?

The stability of ligand-stabilized carboxylic acid derivatives (such as esters, amides, anhydrides, and acid halides) with terminal GeTe bonds is highly questionable as there is no report on such compounds. Nevertheless, we are able to isolate germatelluroester [LGe­(Te)­Ot-Bu] (4), germatelluroamide [LGe­(Te)­N­(SiMe3)2] (5), and germatelluroacid anhydride [LGe­(Te)­OGe­(Te)­L] (6) complexes (L = aminotroponiminate (ATI)) as stable species. Consequently, the synthetic details, structural characterization, and UV–vis spectroscopic and theoretical studies on them are reported for the first time.
