2-Phenoxy-4,4-dimethyltetrahydro-2H-1,3,4,2-oxadiazaphosphorinium 2-oxide innersalt, the first known cyclic phosphaminimide, was synthesized by dehydroiodination of its hydrazinium salt. The corresponding 2-phenyl derivative was unstable and not isolated. The 2-phenoxy and 2-phenylphosphorinium iodides and their precursors produced weak inhibition of sympathetic ganglionic transmission. The phosphaminimide
通过对肼盐进行碘代氢碘化反应,合成了2-苯氧基-4,4-二甲基四氢-2 H -1,3,4,2-氧杂氮杂磷鎓二氧化物内盐,这是第一种已知的环状磷酰胺。相应的2-苯基衍生物不稳定且未分离。2-苯氧基和2-苯基磷鎓碘化物及其前体对交感神经节传递的抑制作用较弱。磷氨基亚胺引起轻微的增强作用,并且也被发现毒性小于其相应的碘化肼盐前体。
Solvent‐free Synthesis and Properties of Functionalized Hydrazines and Bishydrazines as Energetic Ingredients for Propulsion Applications
energetic properties as well, namely for propulsion applications. A novel and scalable synthesis has been developed for a new family of bishydrazines, starting from monomethylhydrazine (MMH). This solvent‐free route represents a suitable alternative to the one described in the literature. It was extended to design a new family of unsymmetrical hydrazines bearing various functional groups. A selected
功能化的肼和双肼是获得较高含氮化合物的有趣且直接的前体。它们还提供结构多样性和有希望的能量特性,即用于推进应用。从一甲基肼(MMH)开始,已经开发了一种新颖且可扩展的合成用于新的联肼家族。这种无溶剂方法是文献中所述方法的一种合适替代方法。它被扩展为设计一个带有各种官能团的不对称肼的新家族。选定的一系列有前途的化合物,经硝化的基团(氨基,肼基或叠氮基官能团)致密化,被认为是一类可能的液体推进剂。确实,通过在双推进剂系统中计算肼的形成热和比冲值,证明了这种肼的积极性。这导致了与MMH / N相当的理论能量表现今天已经在使用2 O 4系统。
Energetic Nitrogen‐Rich Polymers with a Tetrazene‐Based Backbone
New energeticpolymers were synthesized from monomers containing a trans‐2‐tetrazene unit. In contrast to traditional binders, such as inert hydroxytelechelic polybutadiene or glycidyl azide polymers—in which the energetic features are on the side chains—the energetic groups in the polytetrazenes are incorporated directly in the polymerbackbone. Thermal analyses demonstrated that decomposition occurs
