__Diels-Alder Reaction of 2,3-dimethyl-1,3-butadiene & Maleimide (Double Quant)__ ** Conducted by: Student A + Student B  (This experiment was also carried out with half quantities and the same reagents by Students E + F)

// Materials: // - HP-500 Teflon Microwave Reaction Vessel (and all components: torque wrench, sleeve(s) top load disk, microwave vessels). - Microwave vessels (multiple) - Digital scale (1-3) - Melting Point Determinant Apparatus - Trays (to retain & weigh dried product) - Components to //vacuum filtration unit//: - Vacuum tubing (1) - Side port flask (125 mL) - Filter top, with rubber stopper - Filter paper - 10 mL graduated cylinder (1) - Glass plate (1) - Spatula (1) - Capillary tubes - 5 mL test tubes (for storing of dry product)

// Chemical Reagents & approx. Quantities // - Soapy water (N/A) - Acetone (N/A) - DI Water (~20.0 mL) - Maleimide (~3.5g) - 2,3-dimethyl-1,3-butadiene (~5.0 mL)

Conducted by: Student C + D
 * __Diels-Alder Reaction of 2,3-dimethyl-1,3-butadiene & Fumarate__ **

// Materials: // - HP-500 Teflon Microwave Reaction Vessel (including torque wrench, sleeve, stir bar, top load disk) Note: the bright orange glove is used for protection because when the samples come out they could still be hot from the microwave. So always be careful and of course always wear safety goggles and rubber gloves when working in a lab!
