摘要:
Novel mono- or dicarboxytetralinephosphonic acids of the general formula I ##STR1## in which R stands for hydrogen or an alkyl group,X stands for hydrogen or a carboxylic group, andY stands for hydrogen or an alkyl group are made by reacting 1-phenylvinyl-1-phosphonic acid with an unsaturated carboxylic acid of formula II ##STR2## or with its anhydride.
