Jonathan Toledo Lab Performed: 9/16/18 Orgo II lab ,,,,Report Due: 9/17/18 TA: Andrew Mellinger Objective: In this experiment, the Diels alder reaction is being investigated. This experiment uses a diene substrate, anthracene in an 1,4 addition reaction by an activated dienophile, Maleic Anhydride. To complete the reaction, a mixture of the reactants was heated between 180-185 degrees in a sand bath at reflux. Experimental Procedure: Experiments D2 was followed as described in Mayo, pages 271-272, with the modifications listed in the Canvas document. Reagents and Equipment Drierite is substituted for calcium chloride in the drying tube as a drying agent. Reaction Conditions Heat the reaction mixture at a temperature of 180-185 degrees Reaction Scheme: Data and Results: Anthracene Maleic Anhydride Xylenes 9,10-Dihydroanthracene Mol. Formula C14H10 C4H2O3 C18H12O3 Molar Mass (g/mol) 178.23 98.06 276.30 Amount (mg) 80 40 TY: 110 AY: .19 Amount (mL) 1.0 mmol 0.44 0.40 TY: 0.40 AY mp ( ) 133 203-204 bp ( ) 137-140 Observations: Mixture with Xylene solvent has a yellow color and is not as pungent as reactants by
