Abstract EN
Polyethylene glycols (PEGs) were found to be efficient media for decarboxylative nitration of α,β-unsaturated aromatic carboxylic acids by ceric ammonium nitrate (CAN) in acetonitrile to give β-nitrostyrene derivatives.
Kinetics of the reaction exhibited second order kinetics with a first order dependence on [CAN] and [substrate].
Reactions were too sluggish to be studied in the absence of PEG; therefore detailed kinetics were not taken up.
Reaction times were reduced from 24 hrs to few hours.
The catalytic activity was found to be in the increasing order PEG-300 > PEG-400 > PEG-600 > PEG-200.
Mechanism of PEG-mediated reactions was explained by Menger-Portnoy's scheme as applied in micellar kinetics.
