To study the scope and limitations of the use of complexed species of AlCl3 in Friedel-Crafts reactions, we investigated the acetylation and benzoylation of 2(3H)-benzoxazolone and 3-methyl-2(3H)-benzoxazolone varying the amide complexing agent. We replaced DMF by N-methylformamide, dimethylacetamide, pyrrolidinone, N-methylpyrrolidinone, tetramethylurea, and DMSO. However, there was no particular advantage of substituting DMF by another amide ligand. This can probably be ascribed to the fact that the complex formed between AlCl3 and the complexing agent becomes too stable. Alternatively, a route using polyphosphoric acid and microwave activation was explored. The major advantage of running the reaction in a microwave oven was that a good yield was reached in a rather short period of time.
There is still a lot of research devoted to this compound(SMILES：O=C1OC2=CC(C(C)=O)=CC=C2N1)HPLC of Formula: 54903-09-2, and with the development of science, more effects of this compound(54903-09-2) can be discovered.
