Procedure

To each of two 10-ounce crown-capped beverage bottles was charged 1 gram of 50-mesh magnesium shavings (41 mM), followed by 30 ml. of THF and 10 ml. styrene (86.5 mM in THF). To one of the bottles (#1), 38.4 grams of 23.6% 1,3-butadiene in hexane (167 mM) were charged. To the other bottle (#2), 43.5 grams of 23.6% 1,3-butadiene in hexane (140 mM) were charged. Bottle #1 was placed in an ultrasound bath to activate the magnesium metal. Bottle #2 was placed in a 65° C. water bath. After three days at 65° C., most, but not all, of the magnesium in bottle #1 had reacted. The reaction in bottle #2 took longer and some magnesium was still present after seven days at 65° C.
