This minireview provides the chosen examples of our recent discoveries in the polymerization of hydrosilanes, dihydrosilole, lactones, and vinyl derivatives using various catalysts. Hydrosilanes and lactones copolymerize to give poly(lactone-co-silane)s with Cp2MCl2/Red-Al (M = Ti, Zr, Hf) catalyst. Hydrosilanes (including dihydrosilole) reduce noble metal complexes (e.g., AgNO3, Ag2SO4, HAuCl4, H2PtCl6) to give nanoparticles along with silicon polymers such as polysilanes, polysilole, polysiloxanes (and silicas) depending on the reaction conditions. Interestingly, phenylsilane dehydrocoupled to polyphenylsilane in the inert nitrogen atmosphere while phenylsilane dehydrocoupled to silica in the ambient air atmosphere. Cp2M/CX4 (M = Fe, Co, Ni; X = Cl, Br, I) combination initiate the polymerization of vinyl monomers. In the photopolymerization of vinyl monomers using Cp2M/CCl4 (M = Fe, Co, Ni), the photopolymerization of MMA initiated by Cp2M/CCl4 (M = Fe, Co, Ni) shows while the polymerization yield decreases in the order Cp2Fe > Cp2Ni > Cp2Co, the molecular weight decreases in the order Cp2Co > Cp2Ni > Cp2Fe. For the photohomopolymerization and photocopolymerization of MA and AA, the similar trends were observed. The photopolymerizations are not living. Many exciting possibilities remain to be examined and some of them are demonstrated in the body of the minireview.
