> It is better to prevent waste than to treat or clean up waste after it has been created. No, very wasteful > Synthetic methods should be designed to maximize the incorporation of all materials used in the process into the final product. Terrible waste, 3 phenyl groups just lying around. > Wherever practicable, synthetic methods should be designed to use and generate substances that possess little or no toxicity to human health and the environment. Nothing about this lab is healthy or non toxic ﻿however this way doesnt use a harmful solvent. > Chemical products should be designed to effect their desired function while minimizing their toxicity. Again, not sure of the function, but the products arent health tonics. > The use of auxiliary substances (e.g., solvents, separation agents, etc.) should be made unnecessary wherever possible and innocuous when used. Yes, this lab is solvent free. > Energy requirements of chemical processes should be recognized for their environmental and economic impacts and should be minimized. If possible, synthetic methods should be conducted at ambient temperature and pressure. Yes, done at room temp/pressure, and its quick too. > A raw material or feedstock should be renewable rather than depleting whenever technically and economically practicable. Could not find out if triphenyl phosphine oxide is recyclable. > Unnecessary derivatization (use of blocking groups, protection/ deprotection, temporary modification of physical/chemical processes) should be minimized or avoided if possible, because such steps require additional reagents and can generate waste. Yes, this is a one step process. > Catalytic reagents (as selective as possible) are superior to stoichiometric reagents. No catalyst. > Chemical products should be designed so that at the end of their function they break down into innocuous degradation products and do not persist in the environment. Products are not good for the environment. > Analytical methodologies need to be further developed to allow for real-time, in-process monitoring and control prior to the formation of hazardous substances. This is not relevent to this experiment. > Substances and the form of a substance used in a chemical process should be chosen to minimize the potential for chemical accidents, including releases, explosions, and fires. Slight risk of fire, if you put a match to this stuff. Red means meets or is neutral to criteria. Blue means it did not meet the criteria. Thanks again to Haley for the idea.

Thanks for writing this and sharing what you learned with us. I like the selective use of color: that idea works well!
