Treatment of compound (J) with `H_(2),Pd//C`, reduces the double bond to give the corresponding saturated acid, i.e., 3-henylpropanoic acid. The saturated acid on treatment with `SOCl_(2)` gives the corresponding acid chloride which upon subsequent treatment with anhyd. `AlCl_(3)` brings
About cyclization to give the cyclic ketone, (K), i.e., I-indanone.
