A convenient method for the synthesis of magnetically recyclable palladium nanoparticles (Fe3O4-Pd) is described. The catalytic application of the Fe3O4-Pd nanoparticles was explored for the first time in oxidat

A palladium-catalyzed tandem oxidative annulation of primary benzamides with acrylates via intermolecular N-alkenylation followed by intramolecular C-alkenylation yielded a stereoselective synthesis of (E)-3-methyleneisoindolin-1-ones. The study unveils, for the first time, that only E-enamides could undergo intramolecular oxidative cyclization under the optimized conditions to give isoindolinones. The current strategy represents an umpolung strategy when compared to the literature approaches that use benzamides.

A facile and rapid access to multi-substituted oxazoles has been achieved under mild reaction conditions in a short reaction time. Reaction of enamides 1 with [bis(trifluoroacetoxy)iodo]benzene (PIFA) in trifluoroethanol (TFE) at room temperature for 15?min afforded the desired oxazoles 2 in moderate to excellent yields (58–98%). A wide range of functional group tolerance has been observed for these transformations.
Thermolyse von Oxazolin-5-onen, XI. N-Acylimine und Enamide durch Gasphasenpyrolyse von 4-Alkyl-2-oxazoline-5-onen

On gas phase thermolysis 4-alkyl-2-oxazolin-5-ones 1 undergo CO elimination to yield N-acylimines 2, which rearrange into more stable enamides 3 if α-hydrogens are present.N-Acylimines (e.g. 2a) may be isolated in cases where the rearrangement is prevented by a quarternary C-atom.The 4,4-dialkylsubstituted oxazolinone 1o yields mixtures of N-acylimine 2o and enamide 3o, the amount of the latter increasing at higher pyrolysis temperatures.
