The present disclosure provides a process for preparing an aryl ketone of Formula I, comprising reacting a substituted benzene of Formula II with a carboxylic acid of formula IIIa and/or a carboxylic anhydride of formula IIIb in presence of an alkyl sulfonic acid acting as catalyst cum solvent/contacting medium. I, II, IIIa, IIIb, wherein, R.sub.1, R.sub.2, R.sub.3 and R.sub.4 are as defined in the description. ##STR00001##

A method comprising synthesizing a cyclic organic compound via reaction of an unsubstituted or substituted cyclopentene with an unsubstituted or substituted acrylic acid in the presence of phosphoric and/or sulfonic acid reagent to make the cyclic organic compound. Also, a method of synthesizing a ligand for a transition metal, and a related substituted ligand-metal complex and catalyst, from the unsubstituted or substituted cyclopentene and unsubstituted or substituted acrylic acid. Also, the cyclic organic compound, ligand, and substituted ligand-metal complex and catalyst synthesized thereby. Also a method of polymerizing an olefin with the catalyst to give a polyolefin, and the polyolefin made thereby.

Disclosed herein is a process for the conversion of polymers, oligomers, or mixtures thereof into shorter alkanes, carboxylic acids, alcohols, alkyl halides or aldehydes. This process includes contacting the polymers, oligomers, or mixtures thereof with the compound of formula (I):

Al(R.sup.1).sub.3  (I)

where R.sup.1 is independently selected at each occurrence thereof from the group consisting of H, aryl, C.sub.1-C.sub.8 alkyl, and C.sub.1-C.sub.8 alkoxy, as a reaction mixture, in the presence of a catalyst selected from the group consisting of a transition metal catalyst, a lanthanide series metal catalyst, or combinations thereof.
