Reaction of Tetrachalcogenstannolanes with Triphenylphosphine. A Novel Mode of Generation for Overcrowded Stannanethiones and Stannaneselones

Article abstract of DOI:10.1246/cl.1992.1595

Dechalcogenation of overcrowded 1,2,3,4,5-tetrachalcogenastannolanes with triphenylphosphine resulted in the formation of the corresponding 1,3,2,4-dichalcogenadistannetanes via <2+2>cycloaddition of intermediary stannanethione and stannaneselone.Molecular structures of the newly obtained 1,3,2,4-dichalcogenadistannetanes were examined by X-ray analysis.
