Cyclopropene cyclic compound
WebThe simple Hückel description of aromaticity states a ring shaped molecule will be aromatic if it meets certain criteria. One is the species must be flat. Another is it must contain (for a small integer n) 4n + 2 π-electrons. Mathematics tells us three points define a plane. So a cyclopropenyl ring must be flat! WebApr 10, 2024 · The first geometric enantiomers in the cyclic compounds series are reported. The investigated compounds are 2,2‐disubstituted‐5‐methyl‐1,3‐dioxane derivatives in which the substituents at position 2 bear chiral centers with identical substituents but with opposite configurations.
