PROPERTIES OF THE BETA-CARBONYLALKYLTIN CHLORIDES - EVIDENCE FOR INTRA-MOLECULAR COORDINATION

The Mössbauer spectra and the solvent effect on the 1H NMR spectra support the conclusions from infrared spectroscopy that the compounds Cl3 SnCR2 CRHCOX and the Cl2 Sn(CR2 CRHCOX)2 (R = Me or H; X = Me, OH, or OAlkyl) are intramolecularly coordinated in both the solid state and in solution. The compounds Cl3 SnCR2 CRHCOX (X = OH or OAlkyl) react with t-butoxyl radicals in solution to show the ESR spectra of the displaced radicals CR2 CRHCOX. © 1979.
