WebDeamination Pre-lab: 1) Prepare your lab notebook for the deamination reaction by drawing a diagram of the lab setup and integrating the procedural information into the diagrams. Indicate whether the contents of each container at the end of the experiment goes to organic waste, halogenated waste, or down the drain. Use as few words as possible. WebThe ester groups remained intact as expected (Equations 1-4). The diazomethyl ketones, which forms besides the diazooxoaldehydes in the diazotization reaction, do not interfere this condensation (Equation-5). Therefore the diazooxoaldehydes may be safely employed as mixtures with diazomethyl ketones.
