Isolation of a Stable, Acyclic, Two-Coordinate Silylene
Abstract
The synthesis and characterization of a
stable, acyclic two-coordinate silylene, Si(SArMe6)2,
(ArMe6 = C6H3-2,6(C6H2-2,4,6-Me3)2) by reduction of
Br2Si(SArMe6)2 with a magnesium(I) reductant is described.
It features a v-shaped silicon coordination
with a S-Si-S angle of 90.519(2)° and an average Si-S
distance of 2.158(3) Å. Although it reacts readily with
an alkyl halide, it does not react with hydrogen under
ambient conditions probably as a result of the ca. 4.3
eV energy difference between the frontier silicon lone
pair and 3p orbitals.
