摘要
Cucurbituril has a high symmetry and rigid structure.When cucurbit[6]uril（CB[6]） was nitrolyzed with the mixed solution of acetic anhydride in fuming nitric acid,nitroform（NF） was generated.NF also can be obtained by the nitration of both CB[5,7,8].This nitration procedure provides a lower risk,inexpensive,new preparation of nitroform,and the reaction condition of this new method is very mild.
