A series of ammonium monosubstituted H ‐phosphonate salts were synthesized by combining H ‐phosphonate diesters with amines in the absence of solvent at 80 °C. Variation of the ester substituent and amine produced a range of ionic liquids with low melting points. The products and by‐products were analyzed by spectroscopic and spectrometric techniques in order to get a better mechanistic picture of the dealkylation and formal dearylation observed. For dialkyl H ‐phosphonate diesters, (RO) 2 P(O)H (R=alkyl), the reaction proceeds via direct dealkylation with the reactivity increasing in the order R= i Pr
