Polymerization via Reaction at Metal Bond

Many polymerizations used to synthesize organometallic polymers involve cleavage of a bond to the metal atom of one reactant followed by attachment at that metal of a fragment derived from a second reactant [Carraher et al., 1978 Kaliyappan and Kannan, 2000 Manners, 1996 Nguyen et al., 1999 Pittman et al., 1987 Sheets et al., 1985]. 

A wide range of reactions have been used, but only a few are illustrated here. Carboxylate and sulfide groups have been used to obtain organometallic polymers (Eqs. 2-235 and 2-236). These types of reactions have been used to synthesize organometallic polymers of a wide variety of other metals (e.g., Zr, Hf, Si, Ge, Pb, As, Sb, Bi, Mn, B, Se). The polymer obtained 

The phthalocyanine moiety (LXa), where M represents a coordinated metal, has been incorporated into polymer structures. LXa is abbreviated by structure LXb. One reaction
