The present disclosure describes methods for silylating heteroaromatic derivatives, comprising the use of hydrosilanes and potassium hydroxide.

A process to functionalize organo-zinc compounds with halosilane electrophiles employs a basic additive. The process includes combining the organo-zinc compound, a halosilanes, and a nitrogen containing heterocycle as the basic additive. The presence of the basic additive facilitates successful substitution. Functionalized silanes and silyl-terminated polyolefins can be prepared using this process. The functionalized silanes may be useful as endblockers for polyorganosiloxanes having SiH and/or silicon bonded aliphatically unsaturated groups capable of undergoing hydrosilylation.

Provided is a process for preparing certain silane precursor compounds, e.g., triiodosilane from trichlorosilane utilizing lithium iodide in powder form and catalyzed by tertiary amines. The process provides triiodosilane in high yields and high purity. Triiodosilane is a precursor compound useful in the atomic layer deposition of silicon onto various microelectronic device structures.

The mechanochemical functionalization of silicon nanoparticles and functionalized silicon nanoparticles are described. The processes include applying shear forces to silicon metal the presence of an alkane and thereby functionalizing the silicon with an alkyl-functionalization, preferably an alkyl-hydride-functionalization. The resulting product includes a plurality of silicon nanoparticles each carrying an alkyl-functionalization, and preferably a hydride-functionalization, derived from an alkane.

The process of bi-functionalizing silicon nanoparticles and bi-functionalized silicon nanoparticles are described. The processes include applying shear forces to silicon metal in the presence of an alkane, thereby providing an alkyl-hydride-functionalized silicon nanoparticle, which is then treated with a reactant, e.g., a compound that reacts with the hydride functionality, to provide the bi-functionalized silicon nanoparticles. The resulting product can include a plurality of functionalities on a silicon nanoparticle derived from alkenes, alkynes, aldehydes, alcohols, thiols, amines, carboxylates, and/or carboxylic acids.
