Summary: The first electrochemical study of a compound
containing a SidC double bond, i.e., (t-BuMe2Si)(Me3-
Si)Sid2-Ad, reveals an extremely low oxidation potential
of 0.28 V (vs Ag/AgCl), which is comparable to those of
of the best known organic electron donors.
Since the first report of firm evidence for the existence
of compounds with a SidC double bond (silenes) in
1967,1 several physical properties of transient and stable
silenes have been determined.2-4 However, one of the
most basic physical properties of silenes, their redox
potentials, have not been studied yet. Here we report
