Electrophilic Reactions of 5-Aryltetrazoles: Synthesis of Isomeric 2-(Adamantan-1-Yl)-5-Nitrophenyl-2H-Tetrazoles and their Derivatives

Multisubstituted Imidazolo[4,5-d]pyridazine Fused Ring System Resulting from Nitroamine–Nitroimine Tautomerism

“…The sensitivity is a key property in deciding the application of energetic materials. The impact (IS) and friction (FS) sensitivities were obtained by using standard BAM drop hammer and friction tester techniques . As shown in Table , NIPI-2 has an acceptable impact sensitivity at 7 J and a friction sensitivity at 160 N. All of its salts ( 2 – 4 ) possess better impact (32–36 J) and friction sensitivities (≥160 N).…”

Synthesis, structure, and antiviral properties of novel 2-adamantyl-5-aryl-2H-tetrazoles

“…The adamantylation of NH-tetrazoles 2a-h in H 2 SO 4 proceeds exclusively at the N-2 nitrogen atom of the tetrazole ring with the formation of 2-(adamantan-1-yl)-5-aryl-2Нtetrazoles 3a-h in high (81-92%) yields. Compounds 3c,d were nitrated with a sulfuric-nitric acid mixture at 8-10°С according to the previously described method 15 to give 2-(adamantan-1-yl)-5-(nitroaryl)-2Н-tetrazoles 3j,k. Compound 3i was obtained by reduction of nitro compound 3g with metallic zinc.…”
