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

open access: bronze, 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 ...

Preparation of diethyl malonate adducts from chalcone analogs containing a thienyl ring [PDF]

open access: diamond, 2010
Nine chalcone-diethyl malonate derivatives (4a-i) were prepared by the reaction of chalcone derivatives (3a-i) with diethyl malonate in the presence of a catalytic amount of KOt-Bu in CH2CI2 in good to excellent yields. The products were characterized by
