The mass spectra of a series of aryltrimethyltins are described and analysed. The main features are: a relatively weak molecular ion, a very important ArSnMe2+ ion (base peak), a low intensity ArSnMe+ fragment and a non negligible ArSn+ peak. These findings may be related to the well known stable valence states of tin (IVSn and IISn) and the unfavourable IIISn and ISn states. Whereas a methyl group is easier to cleave from the ArSnMe3+ ion than the phenyl radical, n-butyl seems to be more strong...

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 alkyl radical from the next higher unfavourable valence state, or by losing an alkene or alkane molecule from a favourable valence state. The ease of cleavage of a carbon‐tin bond in the molecular ion parallels the stabilization of the leaving alkyl rad...

Abstract The mass spectra of four different series of trialkyltin halides are described and analysed. The fragmentation rules are found to be identical to those of other alkyltin systems. The fragmentation pattern conforms to hypothesis of preferred Sn IV and Sn 11 valence state in the tin-containing fragments. The ease of cleavage of a halogen-tin bond in the molecular ion parallels the bond energy in the ground state.

A redistribution of s-character in the tin orbitals of the Sn–C bonds of methyl-substituted tetraorganotins R3SnR' are expected to depend on the steric requirements of the R and R' groups and might be held responsible for the differences found for the J(Sn–C–H) coupling constants.

The synthesis of optically active p‐anisyl‐(3‐hydroxy‐3‐methylbutyl)methyl‐α‐naphthyl tin (IV) is described. The spectroscopic properties of this compound and of the products used as synthesis intermediates are given. The two diastereoisomers of (‐)‐menthyl‐β‐(methylnaphthyl‐phenylstannyl)‐propionate (V) could not be separated. Copyright © 1975 Wiley‐VCH Verlag GmbH & Co. KGaA, Weinheim

Nine new racemic organotin derivatives: MePriPrSnR (R = Br, Et, Bu, iBu, sBu, tBu) and MeiPrcycloHexSnR′ (R′ = Br, Et, anisyl) have been synthesized in high yields. Their mass spectra and those of some intermediates are given and discussed on the basis of previous results. Copyright © 1969 Wiley‐VCH Verlag GmbH & Co. KGaA, Weinheim

The 1H NMR spectra in the pyridine proton region of six 2,6‐pyridinedicarboxylato‐(phenyl) (organo)tin(IV) compounds in DMSO‐d6 solutions exhibit a pattern that, together with 13C coupling data and 119Sn chemical shifts, can be interpreted by a heptacoordinated pentagonal bipyramidal structure in which the tin atom is likely to be surrounded by two DMSO ligands in equatorial positions.
