Method/Apparatus/Procedure:
   The synthetic method was used. Miscibility was determined in a glass-stoppered tube of 4 mm inside diameter. Equal volumes (0.1 mL) of (1) and (2) were measured into the tube which was then strapped to a thermometer, warmed to 5 or 10 °C above the solubility temperature, mixed well by shaking, and then allowed to cool slowly, still shaking, in a bath of white oil, water or (below 0 °C) non-freezing mixture.

Source and Purity of Materials:
   (1) Not specified.
   (2) Some alkadienes(*) were obtained from Dr. F. Cortese; others were purest commercial samples available from BDH.
