Abstract
The reaction between particular styrenes and particular alkenes to produce alkyl substituted indanes has been discovered to give improved yields when phosphoric acid is used as the catalyst. The catalyst is readily separated from the organic products at the end of the reaction and can be used repeatedly to catalyze further reactions. The product further comprises novel adducts of the alkene and styrene which are converted into the desired isochroman products when the indanes are used as intermediates in the production of isochromans.
