Class RearrangementLonePairReaction

java.lang.Object
org.openscience.cdk.reaction.ReactionEngine
org.openscience.cdk.reaction.type.RearrangementLonePairReaction
All Implemented Interfaces:
IReactionProcess

public class RearrangementLonePairReaction extends ReactionEngine implements IReactionProcess

IReactionProcess which participate in movement resonance. This reaction could be represented as |A-B=C => [A+]=B-[C-]. Due to excess of charge of the atom B, the double bond in the position 2 is displaced.

Make sure that the molecule has the correspond lone pair electrons for each atom. You can use the method:

 LonePairElectronChecker 

It is processed by the RearrangementChargeMechanism class

  IAtomContainerSet setOfReactants = DefaultChemObjectBuilder.getInstance().newAtomContainerSet();
  setOfReactants.addAtomContainer(new AtomContainer());
  IReactionProcess type = new RearrangementLonePairReaction();
  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.
