On the catalytic transformation of furan amines to 2,4-dialkylpyrroles

Conclusions In hydrogenation in the vapor phase on a skeletal nickel-aluminum catalyst at 290–300°, 1 -furyl-2-alkyl-3-aminopropanes are convened as a result of conjugated hydrogenolysis of the furan ring at the 1,5-1,5- and 4,5-, as well as 1,5- and 3,4-bonds, to 2-methyl-, 2-ethyl-, and 2-n-propyl-4-alkylpyrroles, in yields of 30, 25, and 45%, respectively.Translated from Izvestiya Akademii Nauk SSSR, Setiya Khimicheskaya, No. 6, pp. 1118–1120, June, 1964
