Abstract
The telomerization of butadiene with diethylamine with the formation of the tertiary amine (C2H5)2NC8H13 is catalyzed by Ni, Pd and Pt allyl halide complexes. Triphenylphosphine increases the activity of such catalysts. The rate of telomerization depends strongly on the [PPh3]/[M] ratio (M=Pd and Pt) and increases in the series of metals: Ni<Pt<Pd. The activity of (π-C3H5PdCl)2 exceeds that of (π-C3H5)2 Pd by more than two orders of magnitude.
Abstract
Под влиянием аллилгалогенидных комплексов Ni, Pd и Pt протекает теломеризация бутадиена с дизтиламином с образованием третичного амина (C2H5)2NC8H13. Трифенилфосфин повышает активность таких катализаторов. Скорость теломеризации зкстремально зависит от отношения [PPh3]/[M], M=Pd и Pt, и возрастае↦ в ряду металлов: Ni<Pt<Pd. Активность (π-C3H5PdCl)2 более чем на два порядка превышает активность (π-C3H5)2Pd.
