Kimura, Toshihiro; Kamata, Keigo; Mizuno, Noritaka published the artcile< Bifunctional Tungstate Catalyst for Chemical Fixation of CO2 at Atmospheric Pressure>, Name: (9Z,12Z)-Methyl octadeca-9,12-dienoate, the main research area is aromatic diamine propargylic alc carbon dioxide fixation tungstate catalyst; heterocycle cyclic urea carbonate quinazolinedione preparation reaction mechanism.
The authors report the first example of tungstate-based catalytic fixation of carbon dioxide (CO2). A simple monomeric tungstate, TBA[WO4] (TBA = n-Bu4N+) acts as a highly efficient homogeneous catalyst for chem. fixation of CO2 with aromatic diamines, 2-aminobenzonitriles, and propargylic alcs. to give urea derivatives quinazoline-2,4(1H,3H)-diones, and cyclic carbonates, resp. The 1H and 13C NMR spectra show the specific interaction of the tungsten-oxo moiety in TBA[WO4] with both CO2 and the substrate. This study also shows the importance of developing bifunctional catalysts which can activate both CO2 and a nucleophile (amines, alcs., etc.).
