The dinitramide salts of ammonia (ADN), hexamethylenetetramine (HDN), potassium (KDN), and sodium (NaDN) showed a linear relationship between the DSC rate of decomposition at the peak maximum and the DEA tan5 value at the low temperature transition peak. As the cation basicity increased in the series ADN < HDN < KDN
Indolo[1,2‐c] quinazolines, indolo[1,2‐d] [1,4]benzodiazepines, indolo [1,2‐d] [1,4]benzodi‐azepin‐6‐ones and benzimidazo[1,2‐d] [1,4] benzodiazepin‐6‐ones were synthesized. In an acid medium, the indoloquinazolines were produced from 2‐(o‐aminophenyl)indole and acyl halides. However, in the presence of sodium acetate, the acylated amine was obtained and was cyclized to the indolobenzodiazepinones using sodium hydride. The syntheses are described in detail and characterization data are given.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
