Lecture 2: MIGRATION REACTIONS also known as "Migratory Insertions"

Formal Definition:

Insertion of an unsaturated ligand (Y) into an adjacent M-X bond.

Mn+ dn	[dn-2]	Mn+ dn

Y = CO, C₂H₄, C₂H₂ Benzene, Cyclopentadienyl

X = H, R, Ar, C(O)R

L = Lewis Base, Solvent, PR₃, NR₃, R₂O

Contrast

Intermolecular nucleophilic attack on M-Y bond
