초록

A process for the hydrogenolysis of 2,4,6,8,10,12-hexabenzyl-2,4,6,8,10,12-hexaazatetracyclo[5.5.0.0.sup.5,9.0 .sup.3,11 ]dodecane ("HBIW") is disclosed. In the process, a quantity of HBIW, a cosolvent, and a bromine source are placed into a reaction vessel. Acetic anhydride and a palladium hydrogenolysis catalyst are rapidly added to the reaction vessel. The hydrogenolysis catalyst should be substantially free of water. The reaction vessel is purged of an atmosphere capable of reacting with hydrogen, and hydrogen is quickly introduced into the reaction ...
