| Abstract: | The reaction of isoprene with aniline, catalyzed by the Pd(acac)2-(RO)3P-CF3CO2H system, 1 : 4 : 4 [R = Me, Et; acac = (CH3CO)2CH], in MeCN provides N-(3-methylbut-2-en-1-yl)aniline with a high selectivity (up to 84%) and a nearly quantitative yield (75%). At 1 : 4 : 20 and 1 : 4 : 40 molar component ratios in the catalytic system, up to 28–31% of N,N-(2,3-dimethylprop-2-en-1-yl)aniline is formed. Telomeric reaction products appear at 1 : 2 : 4 and 1 : 1 : 10 ratios.__________Translated from Zhurnal Obshchei Khimii, Vol. 75, No. 6, 2005, pp. 963–968.Original Russian Text Copyright © 2005 by Petrushkina, Mysova, Orlinkov. |
