| Summary: | The main focus of this experiment was synthesizing 2,3-dioxopyrrolidine for the first part. There
were three main reagents to achieve the first part of this experiment. The reagents were diethyl
oxalate, methyl amine and aldehyde groups. The two different aldehyde groups used were
anisaldehyde and benzaldehyde. The structures of the 2,3-dioxopyrrolidine were determined
using NMR. The second part of this experiment is decarboxylation. Each product from the first
part underwent reflux for 2 hours in 10% HCl. The mixture obtained from decarboxylation was
extracted with dicholomethane and ethyl acetate. The mixture then evaporated under reduced
pressure. |
