Synthesis and Characterization of the CIS and TRANS Isomers of Ph₃Sn‐CHCH‐C(OH)RR' Compounds and their GEM Analogs. Evidence for an Intramolecular HO→Sn interaction In the solid and Solution State

The cis and trans isomers of compounds of the type Ph 3 Sn‐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 13 C and 119 Sn Secondary Isotope Multiplet of Partially Labelled Entities (SIMPLE) NMR. We correlate...
