High-pressure NMR spectroscopy: An in situ tool to study tin-catalyzed synthesis of organic carbonates from carbon dioxide and alcohols. Part 2 [1]

The direct synthesis of diisopropyl carbonate from carbon dioxide and using n-Bu2Sn(OCH(CH3)2)2 (2) as an organometallic precursor was investigated by multinuclear HP-NMR spectroscopy. The study has demonstrated the exclusive formation of an unprecedented tetraorganodistannoxane species, characterized as the bis[diisopropycarbonatotetrabutyldistannoxane] complex, {[n-Bu2Sn(OC(O)OCH(CH3)2)2]2O}2 {7}2.91
