Surface intermediate species of the 4-isobutylacetophenone adsorption-reaction over fosfotungstic Wells-Dawson heteropoly acid
(Planta Piloto de Ingeniería Química, 2009-12)
Surface adsorbed species of isobutylbenzene and 4-isobutylacetophenone on bulk fosfotungstic Wells-Dawson acid have been screened in the present investigation. The evolution of chemisorbed species towards products was ...
Efficient method for tetrahydropyranylation/depyranylation of phenols and alcohols using a solid acid catalyst with Wells-Dawson structure
(Pergamon-Elsevier Science Ltd, 2002-10)
A simple and efficient procedure to form 2-tetrahydropyranyl acetals of phenols and alcohols is reported. Wells-Dawson heteropolyacid catalyst is used both in bulk form or supported on silica, reaction conditions include ...
Efficient deprotection of phenol methoxymethyl ethers using a solid acid catalyst with Wells-Dawson structure
(Molecular Diversity Preservation International, 2001-11-30)
Deprotection of various phenols from their respective methoxymethyl ethers using an heteropolyacid catalyst was studied. The catalyst was the Wells-Dawson heteropolyacid, used both in bulk or supported on silica. Yields ...
