Process for the preparation of octa-2,7-dienyl-1-amine from butadiene and ammonia in the presence of palladium complex catalyst

摘要

Process for the preparation of octa-2,7-dienyl-1-amine by telomerization of butadiene with ammonia in a two-phase system in the presence of hydrophilic palladium complexes, characterized in that octa-2,7-dienyl-1-amine and octa-1,7-dienyl-3-amine are isolated separately from one another from the reaction mixture present after telomerization, and the octa-1,7-dienyl-3-amine isolated in this way is subjected to an isomerization reaction to form octa-2,7-dienyl-1-amine, and also novel triphenylphosphine mono- and dimethoxytri(sodium sulphonates) and the use of triphenylphosphine trimethoxytri(sodium sulphonates), triphenylphosphine trimethyltri(sodium sulphonates) and triphenylphosphine trifluorodi- and tri(sodium sulphonates) as ligands for the preparation of palladium complexes.
