Diaza-1,3-butadienes as Useful Intermediate in Heterocycles Synthesis
Molecules, 2022 Many heterocyclic compounds can be synthetized using diaza-1,3-butadienes (DADs) as key structural precursors. Isolated and in situ diaza-1,3-butadienes, produced from their respective precursors (typically imines and hydrazones) under a variety of ...

Carcinogenicity of 1,3-Butadiene
Environmental Health Perspectives, 1992 1,3-Butadiene, a high-production volume chemical used largely in the manufacture of synthetic rubber, is a multiple organ carcinogen in rats and mice. In inhalation studies conducted in mice by the National Toxicology Program, high rates of early lethal lymphomas occurring at exposure levels of 625 ppm or higher reduced the development and expression ...

Thermal Decomposition of Vicinal Dinitroalkanes
CHIMIA, 1988 Three sym-tetraalkyl-dinitroethanes 1-3 have been decomposed in solution at 180 to 215 °C. The alkylated 1,3-butadienes 10,12, and 13 are formed by elemination of HNO2.
