Class HyperconjugationReaction

java.lang.Object

org.openscience.cdk.reaction.ReactionEngine

org.openscience.cdk.reaction.type.HyperconjugationReaction

All Implemented Interfaces:

IReactionProcess

public class HyperconjugationReaction
extends ReactionEngine
implements IReactionProcess

HyperconjugationReaction is the stabilizing interaction that results from the interaction of the electrons in a s-bond (for our case only C-H) with an adjacent empty (or partially filled) p-orbital.

Based on the valence bond model of bonding, hyperconjugation can be described as "double bond - no bond resonance"

This reaction could be represented like

[C+]-C => C=C + [H+] 

  IAtomContainerSet setOfReactants = DefaultChemObjectBuilder.getInstance().newAtomContainerSet();
  setOfReactants.addAtomContainer(new AtomContainer());
  IReactionProcess type = new HyperconjugationReaction();
  Object[] params = {Boolean.FALSE};
    type.setParameters(params);
  IReactionSet setOfReactions = type.initiate(setOfReactants, null);
  

We have the possibility to localize the reactive center. Good method if you want to localize the reaction in a fixed point

atoms[0].setFlag(CDKConstants.REACTIVE_CENTER,true);

Moreover you must put the parameter Boolean.TRUE

If the reactive center is not localized then the reaction process will try to find automatically the possible reactive center.
