Reactivity of ditert-butyldimethoxystannane with carbon dioxide and methanol: X-ray structure of the resulting complex

D Ballivet-Tkatchenko, R Burgat, S Chambrey… - Journal of …, 2006 - Elsevier
The synthesis of dimethyl carbonate from carbon dioxide and methanol was studied with
ditert-butyldimethoxystannane under pressure at temperatures⩽ 423K. The formation of
dimethyl carbonate is accompanied by transformation of the stannane into a trinuclear
complex, the structure of which has been determined by single-crystal X-ray diffraction
technique. The relevance of this specie in the catalytic cycle is demonstrated by conducting
recycling runs. A preliminary kinetic study underlines the steric influence of the tert-butyl …
