Estimating the term…
A process for the preparation of organic compounds through C--C bond forming reaction which comprises reacting a diene with a dienophile in the presence of solid acid based on either yttrium, scandium or lanthanum supported on metal oxide supports such as oxides of zirconium or tin or titanium or iron oxide modified by sulphation as catalysts for a period ranging from 5 to 48 hours and recovering the reaction products from the reaction mixture by filtration and removal of the solvent by evaporation followed by column chromatography.
