The conformation and reactivity of butadiene and the bent bond/antiperiplanar hypothesis orbital model
The bent bond/antiperiplanar hypothesis (BBAH) is a useful orbital model explaining the conformational analysis and chemical reactivity of butadiene, the regioselective isomerization of α,β-unsaturated esters to their β,γ-deconjugated isomer, and the stereocontrolled nucleophilic addition of amines to ethyl 2,4- pentadienolate and 1,3-butadienyl sulfone.
