WebMay 1, 2024 · Cyclopropane is also a typical strained hydrocarbon with high heat value attributed to the considerable angular tension caused by three-membered ring structure [27], which is important for improving the energy of fuel. For example, Bojase and co-workers have synthesized a series of cyclopropane compounds named “[n]ivyane” [28]. WebCyclopropane is considered to be one of the smallest cycloalkanes, and most of this class of members are said to be more stable in nature. Some common examples of cycloalkanes are the cyclopentane, Cyclobutane, …
