Synthesis of Ligands for the Functionalization of Magnetic
... The initial tests of the Mukaiyama-Aldol reaction provide valuable insight into the use of reusable catalysts. All three reactions are analyzed by 1H NMR. The NMR of the reaction with no ligand shows no product being made. This supports the necessity of the ligand in catalyzing the reaction. The NMR ...
