Synthesis of Lewis Acid‐Base Adducts Between PCO <sup>−</sup> and Group 13 Lewis Acids
Lewis acid–base adducts between [Na(diox)PCO] (diox = 1,4‐dioxane) and trimethyltriels EMe 3 (E = B‐In) were synthesized and crystallized using 18‐crown‐6 (18c6) as ligand for the sodium ions. In the course of these investigations, we were able to characterize the compounds [Na(18c6)][PCO(EMe 3 ) 2 ] ( 1 : E = B; 2 : E = Al) and [Na(18c6)][PCO(EMe 3 )] ( 3 : E = Ga; 4 : E = In). All compounds were examined by NMR spectroscopy, IR spectroscopy, and elemental analysis. X‐ray structure analysis was performed for compounds 1 , 3 , and 4 . The obtained adducts of negatively charged PCO − anions with Lewis acids illustrate the HSAB concept, as the soft Lewis acids GaMe 3 and InMe 3 always coordinated at the soft phosphorus atom.
