In special situations, some ligands participate in substitution reactions leading to associative pathways these ligands can.

Reaction of ligand substitution

The ligand exchange (substitution/replacement) reactions reflect the strong competency power of the auxiliary aromatic ligands (phen/oxine). Describes some common ligand exchange reactions in complex ions. 1) substitution reactions: mln + l' → mln-1l' + l egs [fe(h2o)6]3+ + 3 acac- four recognized mechanisms for ligand substitution in inorganic chemistry. 1 - pairwise mechanisms dissociative, sn1 type (18e complexes ) or associative, sn2 type (16e complexes) photochemical co or arene substitution in 18e.

  • Ligand substitution the top reaction scheme shows how substitution via a square-pyramidal complex, results in retention of stereochemistry while reaction .

Analogous in many ways to sn2 reactions dissociative ligand substitution is most favored in coordinatively saturated 18e - complexes (eg d. Thus the chloride exchange due to the aquation of the ligand having the lowest equilibrium constant would be more rapid during the early portion of the reaction. The labeling of proteins with heavy atom clusters is of paramount importance in biomedical research, but its detailed molecular mechanism remains unknown.
