Isolation of electronic from geometric contributions to Bergman cyclization of metalloenediynes.
Conformationally constrained ethylene-diamine metalloenediyne compounds exhibit alkyne termini separations that are constant and independent of metal center geometry. Ancillary chloride ligand electron donation into the Bergman cyclization reaction coordinate, however, dramatically influences the observed temperatures.
