ABSTRACT: 2-Butyl-4,9-decadienoic and 2-butyl-4,9-dimethyl-4,9-decadienoic acids, structural isomers of 2-cyclohexylgeranylacetic acid,
which is an active component of the wound healing ointment cygerol, have been synthesized. Hydrocarbon chains C10 have been obtained by the one-pot method of formation of long-chain hydrocarbons, namely, by the telomerization reaction
of 1,3-dienes with nucleophiles catalyzed by palladium complexes. A heterogeneous palladium-zeolite catalyst has been used
for the first time in telomerization of isoprene with piperidine.

ABSTRACT: 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.

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.
