Substitution Reactions of Labile Metal Complexes

摘要: Although not restricted to Group 1 cations, the review paper by Cox and Schneider(1) sets framework for complexation of very labile ions simple ligands then constrasts this with special features be considered macrocyclic ligands. While crown ether complexes there is normally some residual interaction between metal center solvent, contrasts cryptate formation, where an additional step involving shedding remaining solvent as ion fully enters ligand cavity. For main group ions, transition state lies close reactants, still almost solvated, N-donors final stage complexation, corresponding exclusive-to-inclusive complex formation. Cryptand formation Ag+, however, more specific, Ag+-to-N bond first steps after outer-sphere
