摘要：

Choline hydroxide (ChOH) is an effective ionic liquid (IL) that enables the straightforward construction of beta-phosphonomalonates in basic medium. A variety of compounds, including aromatic/heterocyclic and aliphatic aldehydes (1a-p) were reacted with dicyanomethane (2) and diethyl phosphonate (3) to produce the targeted products in good yields (4a-p). The constructed compounds as well as the IL were characterized using spectral H-1, C-13, and P-31 NMR. [GRAPHICS]
