Cyclopropane bond length
WebMay 12, 2014 · Viewed 20k times. 46. In my exam, I was asked why cyclopropane could decolourise bromine water (indicating that it reacted with the bromine). All I could guess was that it is related to the high angle strain in cyclopropane, as the C–C–C bond angle is 60 ∘ instead of the required 109.5 ∘. No book I have read mentions this reaction. WebNov 4, 2014 · In the present manuscript, we examined the crystal structure of (1 ′ R,4 ′ S,4a ′ R,8a ′ S)-6 ′,7 ′-dimethyl- 1 ′,4 ′,4a ′,8a ′-tetrahydrospiro[cyclopropane-1,9 ′-[1,4]methanonaphthalene]-5 ′,8 ′-dione and found that the bond length between atoms connecting diene and the dienophile is somewhat longer than the normal C ...
