Substitution on Complexes of the Trivalent Main Group Metal Ions

Ligand Substitution on Complexes of the Trivalent Main Group Metal Ions 

The readily protolyzed light trivalent metal ions have provided a continuous challenge to mechanistic investigators through the ambiguity which can arise in 

Hexasolventochromium(III) species are generally inert, but the presence of-an alklyl or porphyrin ligand in the first coordination sphere usually results in a considerable labilization to ligand substitution of the Cr(III) center, as is illustrated 

07 when X = H2P207, H3P2O7, H2P07, and H3PO4, respectively. This substitution is followed by an isomerization to the cis isomer, a rapid second substitution, and the subsequent loss of the alkyl ligand.
