  • Process for the preparation of omega-arylalkanoic acids
    Patent number: 5149866
    Abstract: The present inventon pertains to a process for the preparation of omega-arylalkanoic acids of the genral formulaR--Ar--R.sup.1 --COOHwherein R is hydrogen, hydroxy, C.sub.1 -C.sub.8 alkyl, C.sub.1 -C.sub.8 alkoxy, or aryl; wherein R.sup.1 is C.sub.1 -C.sub.4 alkyl; and wherein Ar is an aryl group which can be further substituted with at least one of hydroxy, C.sub.1 -C.sub.8 alkyl, C.sub.1 -C.sub.8 alkoxy, aryl, halide, amino, or acetamido. The omega arylalkanoic acids of the given formula are prepared using catalysts which provide an improvement over the known Willgerodt-Kindler reaction.The present invention also pertains to methods for removing sulfur during the above-described process for the preparation of the omega-arylalkanoic acids.
