4-Dimethylaminophenylpentazole is an unstable, explosive compound that contains the rare pentazole ring, which is composed of five nitrogen atoms. The electron donating effect of the 4-dimethylamino substituent on the phenyl ring makes this compound one of the more stable of the phenylpentazoles. At room temperature, its chemical half-life is only a few hours, although storage is possible at cryogenic temperatures. The compound was first prepared in 1956 along with other substituted phenylpentazoles. Studies have been conducted on various other derivatives, though necessarily limited by the instability of these compounds. Some more highly substituted derivatives, such as 2,6-dihydroxy-4-dimethylaminophenylpentazole, are slightly more stable but conversely, more difficult to make. Current r

| - 4-Dimethylaminophenylpentazole is an unstable, explosive compound that contains the rare pentazole ring, which is composed of five nitrogen atoms. The electron donating effect of the 4-dimethylamino substituent on the phenyl ring makes this compound one of the more stable of the phenylpentazoles. At room temperature, its chemical half-life is only a few hours, although storage is possible at cryogenic temperatures. The compound was first prepared in 1956 along with other substituted phenylpentazoles. Studies have been conducted on various other derivatives, though necessarily limited by the instability of these compounds. Some more highly substituted derivatives, such as 2,6-dihydroxy-4-dimethylaminophenylpentazole, are slightly more stable but conversely, more difficult to make. Current research has focused on forming transition metal complexes of these pentazole derivatives, as the pentazole ring should be stabilised by bonding to the metal centre. (en)
- O 4-dimetilaminofenilpentazol é um composto instável e explosivo que contém um raro anel pentazol, formado por cinco átomos de nitrogênio. O efeito doador de densidade eletrônica do substituinte 4-dimetilamino no anel fenil confere a esse composto uma das maiores estabilidades dentre os fenilpentazois. À temperatura ambiente, sua meia-vida é de apenas algumas horas, mas é possível estocar a substância a baixas temperaturas. O composto foi sintetizado pela primeira vez em 1956, junto de outros fenilpentazois substituídos. Estudos foram conduzidos com vários outros derivados, apesar de bastante restritos em função da instabilidade desses compostos. Alguns derivados mais substituídos, como o 2,6-di-hidroxi-4-dimetilaminopenilpentazol, são um pouco mais estáveis, mas sua síntese é mais complicada. Pesquisas recentes têm focado esforços na formação de complexos de metais de transição desses derivados do pentazol, já que o anel presente deve ser estabilizado por meio de ligações a um centro de coordenação metálico.
