Raw Data for "Reactivity of Ketenyl Anions towards Ammonia"

Ketenyl anions with strong electron-withdrawing groups (R = CN or tosyl) react with NH3 to β-ketoamides, while the phosphinoyl substituteted systems (R = Ph2P(E), E = S, Se) activate all three N-H bonds, resulting in a trianionic triamide. This triamide exhibits a dimeric structure with the six potassium cations forming a unique planar triangular {K6}6+ cluster.

DATASET DESCRIPTION: Single folders were created for all separate compounds, named with the corresponding number in the manuscript. The folders contain subfolders with NMR, IR, and Elemental analysis data respectively. For compound 3PSe, DOSY-NMR and NMR for the heating experiment are inside the NMR subfolder as '3PSe_DOSY' and '3PSe_heating', respectively.
