Résumé :

The cis and trans isomers of compounds of the type Ph3Sn‐CHCH‐C(OH)RR' as well as their gem analogs were synthesized and characterized. Mössbauer spectroscopy enabled to assess the presence of weak intramolecular HO→Sn interactions in the cis and gem isomers in the solid state. In solution, the existence of such coordinations was evidenced by 13C and 119Sn Secondary Isotope Multiplet of Partially Labelled Entities (SIMPLE) NMR. We correlate the results of our NMR experiments with the reactivity of these compounds towards iodine. Copyright © 1994 Wiley‐VCH Verlag GmbH & Co. KGaA, Weinheim
