The mass spectra of mixed tetraalkyltins are described and analysed. The fragmentation pattern is in agreement with the hypothesis of prefered Sn(IV) and Sn(II) valence states in the tin‐containing fragments. These states are reached by losing an a

The P.M.R. spectra of 29 compounds containing a Sn(CH3)3 group have been recorded. The chemical shifts and the coupling constants are related to Tafťs and Hammetťs σ sequences. For polycyclic aromatic tin derivatives, the shift is influenced by th

Permutations may be used to describe the transformations of a given complex MLn into one of the n!/hr, possible isomers. The determination of the n! possible permutations gives all the isomerization paths of this complex occuring by nonbond‐rupture

The reaction between iodine and hexamethyl or hexabutyl ditin is very fast in methanol; the rate is measurable in acetone containing sodium iodide. The rate law is a sum of two terms, the first of which is of first order in both I2 and hexaalkyl diti

The rates of the reactions of tetraalkyltins (R4Sn) with bromine in dimethylformamide and acetic acid solutions and with iodine in acetic acid are found to depend on steric effects (kMe> kEt > knPr), caused by the R3Sn leaving group. Trialkyltin brom
