Synthesis and structure of 1,2,3,4,5-tetrachalcogenastannolanes

Novel cyclic polychalcogenides, 1,2,3,4,5-tetrathia- and tetraselenastannolanes [Tb(R)SnY4 (Y = S, Se; Tb = 2,4,6-tris[bis(trimethylsilyl)methyl]phenyl; R = mesityl or 2,4,6-triisopropylphenyl)], have been synthesized by two routes, i.e., (a) the reaction of dihydrostannanes Tb(R)SnH2 with sulfur or selenium and (b) the lithiation of dihydrostannanes Tb(R)SnH2 or dichlorostannanes Tb(R)SnCl2 with t-BuLi followed by reaction with sulfur or selenium. All the tetrachalcogenastannolanes have been characterized by 1H and 13C NMR and elemental analysis. In addition, Tb(MeS)SnS4 (7b) and Tb(MeS)SnSe4 (8b) have been subjected to single-crystal X-ray diffraction analysis. Both five-membered 7b and 8b have distorted envelope conformation, the former of which is slightly more distorted. The reason for the exclusive formation of five-membered polychalcogenides has been discussed on the basis of the X-ray structural analysis and ab initio calculations for the model ring system H2SiSn (n = 2-6).
