Abstract

AbstractThe solution behaviour and redistribution reactions of tetraorganodistannoxane dimers were investigated by 19F and 119Sn NMR spectroscopy. The variable‐temperature NMR data suggest that both the ‘ladder’ and ‘staircase’ structures exist in solution. Redistribution between two different tetrabutylstannoxanes is rapid on the NMR time scale. The 119Sn 2D EXSY NMR data for [Bu2Sn(F)OSnBu2(Cl)]2 indicate that there is no exchange between exo‐ and endocyclic tin centres.
