1-Oxo-2,2-disubstituted-5-indanyloxy(or thio)alkanoic acids and their salt, ester, anhydride, amide and 5-tetrazolyl derivatives are disclosed. The products display a dual pharmaceutical utility in that they exhibit diuretic, saluretic and uricosuric activity. The acid products are prepared by treating a 2,2-disubstituted-5-hydroxy(or mercapto)-1-indanone with an haloalkanoic acid or ester thereof and, if the ester is employed, hydrolyzing the ester.
