Poly(ferrocenylsilane-block-methacrylates) via Sequential Anionic and Atom Transfer Radical Polymerization
Korczagin, Igor,Hempenius, Mark A.,Vancso, G. Julius
, p. 1686 - 1690 (2004)
A route to 2-bromoisobutyryl end-functionalized poly(ferrocenyldimethylsilane), allowing essentially quantitative end-capping was discussed. Following the formation of the organometallic block by anionic polymerization, a ruthenium-mediated controlled radical polymerization of methyl methacrylate was employed to grow the second block. Well-defined PFS-b-PMMA block copolymers with low polydispersities and controlled compositions were obtained. The use of atom transfer radical polymerization (ATRP) to form the second block implies that a wide variety of (meth)acrylic and other vinyl monomers can be used, which opens the way to novel hybrid organic-organometallic block copolymers and amphiphilic organometallic block copolymers.
Room-Temperature Gold-Catalysed Arylation of Heteroarenes: Complementarity to Palladium Catalysis
Cresswell, Alexander J.,Lloyd-Jones, Guy C.

Tailoring of the pre-catalyst, the oxidant and the arylsilane enables the first room-temperature, gold-catalysed, innate C?H arylation of heteroarenes. Regioselectivity is consistently high and, in some cases, distinct from that reported with palladium ca

Immobilization of biomolecules via ruthenium-catalyzed functionalization of the surface of silica with a vinylsilane
Hreczycho, Grzegorz,Chmielewski, Marcin K.,MacIejewski, Hieronim,Ratajczak, Tomasz,Marciniec, Bogdan
, p. 3605 - 3608 (2013/07/05)
A new ruthenium complex catalyzed procedure for the efficient O-silylation of an SiO-H group on the silica surface of glass beads with controlled pores (CPG) using 1-trimethylsiloxy-3-dimethylvinylsilylpropane leading to Si-O-Si bond formation with the evolution of ethylene is described. The formed linker contains alkyl hydroxyl groups which can be reacted with a nucleoside phosphoramidite unit. The CPG support containing alkyl hydroxyl groups is successfully applied in automatic chemical synthesis of DNA fragments.
