Abstract

The paper describes the synthesis of novel strained hydrocarbons based on a diene of the norbornene series, namely 5-methylene-2-norbornene, using catalytic cyclopropanation with diazomethane. The study demonstrated the possibility of selective cyclopropanation solely along the endocyclic double bond. The physicochemical properties of the hydrocarbons were investigated systematically. These hydrocarbons were shown to have an advantageous combination of high density, low freezing point, and high energy density value. The study’s findings indicate that the compounds synthesized are promising as a component of high-energy-density fuels for modern jet engines.

基于5-亚甲基-2-降冰片烯的新型应变脂环烃

摘要

该论文描述了基于降冰片烯系列的二烯，即 5-亚甲基-2-降冰片烯，使用重氮甲烷催化环丙烷化合成新型应变烃。该研究证明了仅沿环内双键进行选择性环丙烷化的可能性。系统地研究了碳氢化合物的理化性质。这些碳氢化合物被证明具有高密度、低凝固点和高能量密度值的有利组合。该研究的结果表明，合成的化合物有望作为现代喷气发动机的高能量密度燃料的组成部分。
