A convenient procedure for the synthesis of highly enantioenriched allenylsilanes by Johnson orthoester Claisen rearrangement of 1-silyl propargylic alcohols is described. Allenylsilanes are then used as carbon nucleophiles in three-component, Lewis acid mediated additions to in situ generated oxonium ions

The synthesis of a chloro-functionalized six-membered cyclosilazane (Si5N) is reported. Subsequent reductive polymerizations yielded low molecular weight polysilazanes. 1H and 29Si NMR characterization suggest the identity of the reducing metal influences the polysilazane structure. Optical characterization is consistent with extended

Density changes in thin polymer films have long been considered as a possible explanation for shifts in the thickness-dependent glass transition temperature Tg(h) in such nanoconfined systems, given that the glass transition is fundamentally associated with packing frustration during material

The retention behavior and selectivity of 30 kinds of phenyl-modified porous glasses and silicas, prepared from solutions of phenyldimethylchlorosilane, diphenylmethylchlorosilane or triphenylchlorosilane in xylene, were studied by high-performance liquid chromatography using carbamazepine and diphenylhydantoin as model compounds. From the elemental
