资源简介：
The first diphosphaalkenylstannylene stabilized through
complexation
with a carbene NHC–Sn[C(Cl)PMes*]2 1 (Mes* = 2,4,6-tri-tert-butylphenyl; NHC
= :C{N(iPr)C(Me)}2) was isolated and fully
characterized including single crystal X-ray diffraction analysis.
Its reaction with elemental sulfur rapidly gives the cyclic Sn2S2 (dithiadistannetanne) derivative 3, presumably formed by dimerization of a stannathione intermediate.
By contrast, its germanium analogue NHC–Ge[C(Cl)PMes*]2 7 leads to the corresponding monomeric germathione 4 and germaselenone 5. The germaselenone was
more stable than the germathione and could be structurally characterized.
An unusual thermal cyclization reaction of the last one occurs with
an excess of selenium to give the Ge2Se3 (triselenadigermolane)
ring derivative 6.
