Preparation and characterization of 3,5-dinitro-1H-1,2,4-triazole.

Neat 3,5-dinitro-1H-1,2,4-triazole was obtained in quantitative yield from potassium 3,5-dinitro-1,2,4-triazolate and sulfuric acid. The compound was purified by sublimation in vacuo at 110 °C. Pure HDNT is a hygroscopic white solid that is impact and friction sensitive and decomposes explosively upon heating to 170 °C. However, the presence of impurities might lower the decomposition temperatu...

Preparation of SRN1-type coupling adducts from aliphatic gem-dinitro compounds in ionic liquids.

S(RN)1-type coupling adducts are readily prepared by the reaction between a-sulfonylesters or a-cyanosulfones and gem-dinitro compounds in ionic liquids. The reactions progress smoothly and recovered ionic liquids can be used for several iterations, as long as they are washed with water to remove alkali metallic salts. The reaction rate is slower than the corresponding S(RN)1 reaction in DMSO, ...

Bone morphogenetic protein (BMP) signaling plays many roles in skull morphogenesis. We have previously reported that enhanced BMP signaling through the BMP type IA receptor (BMPR1A) in cranial neural crest cells causes craniosynostosis during postnatal development. Additionally, we observed that 55% of Bmpr1a mutant mice show neonatal lethality characterized by a distended gastrointestinal trac...
