Useful:

• General Description: 1,2-Ethenediylbis(trimethylsilane), also known by various synonyms such as 1,2-bis(trimethylsilyl)ethylene, is an organosilicon compound characterized by a central ethene (ethylene) backbone with trimethylsilyl groups attached to each carbon. This structure imparts unique steric and electronic properties, making it useful in organic synthesis, particularly as a protecting group or as a precursor in the formation of silicon-containing polymers or intermediates. Its reactivity is influenced by the presence of the silyl groups, which can stabilize adjacent carbanions or participate in cross-coupling reactions. 1,2-Ethenediylbis(trimethylsilane) is typically a volatile, moisture-sensitive liquid, requiring careful handling under inert conditions.
