Abstract
1,3,5,7-Tetranitroadamantane (TNA) was prepared from adamantane via a five-step route: bromination, halogen-exchange iodation, amidation, hydrolysis and oxidation. The third step, free radical amidation, was catalyzed by AIBN in common glassware instead of photolyzed by ultraviolet in quartz reaction flask and Rayonet photochemical reactor in sollotts method. The results show that the reaction time could be dramatically shortened from 64 h to 30min, and the yield of 1,3,5,7-tetraacetamidoadamantane could be promoted from 51% to 95%. The total yield of TNA from adamantane was promoted to 18% against 8% reported in reference.关键词
