Are diazides really dangerous compounds under ordinary conditions?

An investigation into the stability of three commonly used diazides (1,3-diazido-propane, 1,3-diazido-propan-2-ol, and 1,3-diazido-propanone) was performed. Despite their use in synthesis, no previous investigation of their thermal stability has been repo

Method for preparing diazacyclooctane intermediate and diazacyclooctane

The invention provides a method for preparing a diazacyclooctane intermediate and diazacyclooctane. The preparation method comprises the following steps: synthesizing 1,5-bis(p-toluenesulfonyl)-1,5-diazacyclooctane from 1,3-bis(p-toluenesulfonyl)-1,3-dioxypropane, 1,3-bis(p-toluenesulfonyl)-1,3-propane diamine and sodium methoxide under a temperature condition of 60-100 DEG C; then synthesizing 1,5-diazacyclooctane bromate from 1,5-bis(p-toluenesulfonyl)-1,5-diazacyclooctane, phenol and hydroacetic acid; and finally, synthesizing 1,5-diazacyclooctane from 1,5-diazacyclooctane bromate and sodium methoxide. According to the method, the yield of the 1,5-bis(p-toluenesulfonyl)-1,5-diazacyclooctane can be increased, and the reaction time for synthesizing the 1,5-diazacyclooctane can be shortened.
