Conclusions 1. Two new N-trimethylsilylated carbodiimides with functional substitution, N-carbomethoxy-N′-trimethylsilylcarbodiimide and N-methanesulfonyl-N′-trimethylsilylcarbodiimide were synthesized. 2. The nitration of these carbodiimides using nonacidic nitrating agents proceeds with transfer of the reaction site and leads to N-nitro-N-carbomethoxycyanamide and N-nitro-N-methanesulfonylcyanamide, respectively. 3. The nitration of N-methanesulfonyl-N′-trimethylsilylcarbodiimide using nitrogen pentoxide, similar to the reaction of N-nitro-N-methanesulfonylcyanamide with trimethylsilyl nitrate, leads to the trimethylsilyl ester of methanesulfonic acid. 4. N-Nitro-N-methanesulfonyl cyanamide and N-nitro-N-carbomethoxycyanamide decompose spontaneously with the formation of the corresponding functionally substituted isocyanates.
