WebAug 23, 2024 · In the series of the investigated compounds 1-5, spi- ro[2.4]hepta-4,6-diene (1) shows the strongest influence of cyclopropyl conjugation on molecular structure in the group of doubly unsaturated cyclopropyl hydrocarbons. The conjugation properties of cyclopropane are subject of debate and other references don't support this. WebCycloalkanes are very similar to the alkanes in reactivity, except for the very small ones, especially cyclopropane. Cyclopropane is significantly more reactive than what is expected because of the bond angles in the ring. Normally, when carbon forms four single bonds, the bond angles are approximately 109.5°.
