silanyl
Silanyl is a term used in organosilicon chemistry to denote a silicon-centered substituent based on the silane framework, typically the silanyl group SiH3 attached to a parent molecule. In this context, silanyl refers to the SiH3– unit and its connectivity to the rest of the molecule. The term is related to the broader family of silyl groups, but silanyl emphasizes a hydrosilane-derived fragment and is sometimes distinguished from more common silyl protecting groups such as trimethylsilyl (TMS).
Chemical structure and reactivity: A silanyl fragment consists of a silicon atom bonded to three hydrogen atoms
Synthesis and applications: Silanyl groups can be introduced through reactions that generate Si–H bearing silicon centers,
Safety: Silane-related species, including silanyl fragments, are typically moisture- and air-sensitive and may be flammable or
