Me2SiH2, MeSiH3, and SiH4 are gaseous and flammable silanes that are inconvenient to use in chemical reactions. Catalytic amounts of a nickel pincer complex and NaOtBu are reported to allow the synthesis of alkyl hydrosilanes from alkenes and alkoxy hydrosilanes, leading to the replacement of Me2SiH2, MeSiH3, and SiH4 by Me2(MeO)SiH, Me(EtO)2SiH, and (MeO)3SiH in hydrosilylation reactions of alkenes. The scope and mechanism of the reactions are also described.

The branching topology of end groups attached to several series of oligothiophenes has a systematic effect on thermal and electrical properties of the oligomers. The series were synthesized in a modular approach and show a distinct drop of the melting point Tm on increasing bulkiness of the substituents. The same trend can be found for the dissociation temperatures Tdis of aggregates in solution. Similarly, monolayer OFET mobilities μFET are significantly decreasing with increasing bulkiness of the substituents. A simple geometric model is presented quantitatively correlating the transition temperatures and mobilities with the substituents' structure based on a bulkiness parameter P, which allows predicting Tm, T dis, and μFET of corresponding not yet synthesized oligomers with branched substituents. This model might be generally applicable for end-capped rod-like conjugated oligomers.
