Synthesis and characterization of silicon-containing block copolymers from nitroxide-mediated living free radical polymerization
High etch resistance to oxygen plasma for silicon-containing polymers, and the high thermal and mechanical robustness of the etching product, silicon oxide, make it attractive to design novel silicon-containing block copolymers for direct patterning of na

A novel synthesis of 4B-element-containing styrene derivatives
To synthesize 4B-group element-containing styrene monomers, alkylmetalation reactions of 4-methylstyrene (1) in the presence of lithium diisopropylamide (2) were investigated. Trialkylsilylation of 1 proceeded easily by the reaction with trialkylsilyl chloride in the presence of 2 to form mono- and bis-trialkylsilylated methylstyrene. This synthetic method was expanded to other 4B-elementcontaining styrenes such as germyl and stannyl compounds.
