Green Chemistry Diels-Alder reaction Hydrophobic effect Spectroscopy 

This experiment demonstrates Green Chemistry through the Diels-Alder reaction, which is an important reaction in organic chemistry because it is an important method of ring formation. The green components of this experiment include attention to atom economy and waste reduction, but the most important green aspect is the use of water as the solvent. Not only is water an environmentally benign solvent, but it also actually improves other aspects of this reaction due to hydrophobic solvent effects. 

The hydrophobic effect is the property that nonpolar molecules tend to self-associate in the presence of aqueous solution. Two explanations have been advanced to explain why the hydrophobic effect increases the rate of reaction for selected Diels-Alder reactions. The first is that the activated complex is somewhat polar it is stabilized by hydrogen-bonding, which makes the reaction go faster. The second is that the hydro-phobic effect acts to force the two reagents together with a solvation shell and to increase the interaction between them. 

All aqueous waste can be disposed of in a waste container designated for nonhalo-
