oxides to crotonaldehyde and cinnamaldehyde has been determined and is dictated by frontier orbital interactions and secondary orbital interactions as well. In cycloadditions to α,β-unsaturated compounds the directive effect of the frontier orbital interactions can be diverted by steric drifts and secondary orbital interactions.

化学,并且也由边界轨道相互作用和次级轨道相互作用决定。在α,β-不饱和化合物的环加成反应中,前沿轨道相互作用的定向效应可通过空间漂移和次级轨道相互作用来转移。
