Tin-chalcogen double-bond compounds, stannanethione and stannaneselone: Synthesis, structure, and reactivities

The first isolation of diarylstannanethione (tin-sulfur double-bond compound) and diarylstannaneselone (tin-selenium double-bond compound), Tbt(Ditp)Sn=X (Tbt = 2,4,6-tris[bis(trimethylsilyl)methyl]-phenyl; Ditp = 2,2″-diisopropyl-m-terphenyl-2′-yl; X = S

Stable stannaneselone and diselena-stannirane: Novel organotin compounds derived from an extremely hindered tetraselenastannolane

The first kinetically stabilized stannaneselone, Tbt(Ditp)Sn=Se (Tbt = 2,4,6-tris[bis(trimethylsilyl)methyl]phenyl; Ditp = 2,2″-diisopropyl-m-terphenyl-2′-yl), with a tin-selenium double bond and a stable diselenastannirane, Tbt(Ditp)SnSe2 were synthesized by deselenation of the corresponding tetraselenastannolane, Tbt(Ditp)SnSe4 with 3 equiv. and 2 equiv. triphenylphosphine, respectively. The X-ray structural analysis of the stannaneselone revealed that it has a trigonal planar structure with the Sn-Se bond length of 2.375(3) ?, which is approximately 9% shorter than that of the corresponding single bond and the shortest among Sn-Se bond lengths so far reported. The molecular structure of diselenastannirane determined by X-ray analysis shows that it has an unusually long Se-Se bond (2.524 ?), about 0.2 ? longer than a typical Se-Se single bond.
