Abstract:
A method for preparing a difunctional aliphatic organic compound which comprises:a) reacting a cycloalkanone of the general formula ##STR30## wherein x is an integer from about 2 to 9; each R is the same or different and is hydrogen, a linear or branched alkyl, an alkylaryl, a hydroxyl or a halogen, with a compound of the general formula ##STR31## wherein R.sup.1 is hydrogen or alkyl; R.sup.2 is --COOH or a salt thereof, --CN, --CONH.sub.2 or COOR.sup.3 wherein R.sup.3 is a linear or branched alkyl or aryl in the presence of a catalyst to form an intermediate reaction product of the general formula ##STR32## wherein x, R, R.sup.1 and R.sup.2 have the aforestated meanings; and, b) subjecting the intermediate reaction product to ultraviolet radiation in the presence of a solvent to provide the product difunctional aliphatic organic compound of the general formula ##STR33## wherein R.sup.4 is derived from the solvent and is hydroxyl, --NH.sub.2 or --OR.sup.5 wherein R.sup.5 is an alkyl or aryl, and x, R, R.sup.1, and R.sup.2 have the aforestated meanings.
