Preferred Label : multi-centre reaction;
Obsolete resource : true;
IUPAC definition : a synonym for pericyclic reaction. the number of centres is the number of atoms not
bonded initially, between which single bonds are breaking or new bonds are formed
in the transition state. this number does not necessarily correspond to the ring size
of the transition state for the pericyclic reaction. thus, a diels–alder reaction
is a four-centre reaction. this terminology has largely been superseded by the more
detailed one developed for the various pericyclic reactions.;
