Abstract

Glycerol was reacted with CO2 (5MPa) at 450K in presence of Sn-catalysts (n-Bu2Sn (OMe) 21, n-Bu2SnO 2 or Sn (OMe) 23), using either glycerol or tetraethylene glycol dimethyl ether (tedmg) as reaction medium. 1 was much more active than 2. 1 was demonstrated to convert into n-Bu2Sn (glycerol-2H) 4 upon reaction with glycerol and elimination of MeOH. Monomeric 4 is proposed to be the active species in catalysis. It converted into a ...
