Analysis reaction pathways using CSD data: attack of a nitrogen nucleophile on a carbonyl centre (after Bürgi & Dunitz, 1986). (a) Substructure search fragment and geometrical parameters used to locate and plot the reaction pathway, and (b) plot of the nonbonded N⋯C distance (d1) versus the increasing pyramidality at the carbonyl C atom, measured by the parameter Δ in part (a). |
