The present invention relates to a method of producing an aliphatic nitrile by reacting an aliphatic carboxylic acid, by reacting an aliphatic dicarboxylic acid or their alkyl esters (the alkyl group with 1 to 5 carbon atoms) with ammonia in the presence of a catalyst of titanium oxide supported on solid silica. In addition, the present invention relates to a method of producing an aliphatic amine, including hydrogenating the aliphatic nitrile by using a hydrogenating catalyst and a catalyst for producing an aliphatic nitrile.

Generation of reactive α-oxogold carbene intermediates via gold-catalyzed oxidation of alkynes has become an increasing versatile strategy of replacing hazardous diazo carbonyl compounds with benign and readily available alkynes in the development of efficient synthetic methods. However, one of the hallmarks of metal carbene/carbenoid chemistry, i.e., insertion into an unactivated C(sp(3))-H bond
