EXPERIMENTAL SECTION Reaction Procedure. The device shown in Figure 2 (a) consists <strong>of</strong> a thick glass reaction bulb with a long capillary neck. The reactor is inverted and several glass beads are added followed by solid reactants through the end opposite to the capillary. The reactor is sealed at the constriction Figure 2 (b). The vessel is then suspended in glass wool in the interior <strong>of</strong> a stainless steel reaction tube having a long neck to house the capillary section <strong>of</strong> the vessel. The entire apparatus is evacuated, pressured with Dz gas, closed <strong>of</strong>f and shaken at the desired temperature in a fluidized sand bath. When the reaction is complete, carbon disulfide is added and products removed for analysis using a long syringe needle. In the absence <strong>of</strong> gas generation within the tube, our observation has been that little or no material is lost from the interior <strong>of</strong> the bulb. Control experiments in which a hydrogenation catalyst was deliberately added showed complete saturation <strong>of</strong> aromatic compounds under the reaction conditions. REFERENCES 1. a.
