Acute environmental toxicity and persistence of DEM, a chemical agent simulant: Diethyl malonate. [Diethyl malonate] [PDF]

open access: green, 1990
The purpose of the following chemical simulant studies is to assess the potential acute environmental effects and persistence of diethyl malonate (DEM). Deposition velocities for DEM to soil surfaces ranged from 0.04 to 0.2 cm/sec. For foliar surfaces, deposition velocities ranged from 0.0002 cm/sec at low air concentrations to 0.05 cm/sec for high ...

An efficient [bmim]oh catalysed the condensations of aromatic aldehydes and diethyl malonate

open access: diamondVietnam Journal of Science, Technology and Engineering, 2018
The rapid and green procedure for the Knoevenagel reaction between aromatic aldehydes and diethyl malonate was developed by using 1-butyl-3- methylimidazolium hydroxide, [Bmim]OH, as an efficient catalyst.

Diethyl 2-[(morpholin-4-yl)(phenyl)methyl]malonate

open access: greenActa Crystallographica Section E Structure Reports Online, 2007
In the title compound, C18H25NO5, the morpholine unit adopts an almost ideal chair conformation. The crystal structure is consolidated by C—H⋯O inter­molecular hydrogen-bond inter­actions, providing stabilization. The mol­ecular conformation shows two possible pockets ready to coordinate two metal atoms.
