The reaction of the oxocumulene ylide ketenylidenetriphenylphosphorane, Ph,PC=C=O (1), with an excess of water in THF yields a white microcrystalline solid, methyltriphenylphosphonium hydrogencarbonate, which contains one molecule of crystallization water, [Ph3MeP](CO3HH2O)-H-. (2). Compound 2 was characterized by IR, multinuclear NMR and ESI mass spectra. The chemical constitution was confirmed by X-ray crystal analysis. On heating, compound 2 decomposes giving CO2, H2O, C6H6 and Ph(2)MepO.

Abstract
The reaction of the oxocumulene ylide ketenylidenetriphenylphosphorane, Ph,PC=C=O (1), with an excess of water in THF yields a white microcrystalline solid, methyltriphenylphosphonium hydrogencarbonate, which contains one molecule of crystallization water, [Ph3MeP](CO3HH2O)-H-. (2). Compound 2 was characterized by IR, multinuclear NMR and ESI mass spectra. The chemical constitution was confirmed by X-ray crystal analysis. On heating, compound 2 decomposes giving CO2, H2O, C6H6 and Ph(2)MepO.File in questo prodotto:
