Formation of a pentacoordinate 1,2-oxastannetanide by novel base-induced rearrangement of a bis(β-hydroxyalkyl)stannane

Article abstract of DOI:10.1080/10426509708545672

Treatment of a bis(β-hydroxyalkyl)diphenylstannane with potassium hydride in THF in the presence of 18-crown-6 gave the corresponding pentacoordinate t-alkoxy-1,2-oxastannetanide as stable crystals instead of a hexacoordinate stannate with two oxetane rings. This compound is considered to be formed by novel tin-1,3-migration reaction from carbon to oxygen reaction involving the formation of an oxetane ring and the subsequent tin-carbon bond cleavage.
