Popis:	The reaction of isoprene with aniline, catalyzed by Pd (acac)2–(RO)3P-CF3COOH, (1:4:4) (R = Me, Et, acac = (CH3CO)2CH-) in MeCN solution, results in high (up to 89 mol.%) selectivity of N–(3-methyl-2-buten-1-yl) aniline. The presence of telomeric products in the reaction mixture is observed at a P/Pd ratio of 1:2 and 1:1. The use of (1,1,1-trifluoro, 4-perfluorocyclo hexyl -2,4-butanedionato) palladium as the catalyst gives rise to 92 mol% mol.selectivity of telomers by the favored tail-to-head and head to head coupling.
