Método para la telomerización selectiva de dienos sustituidos, catalizada por paladio

A method for the selective synthesis of a tail-to-head, or a head-to-head, or a tail-to-tail telomer from an unsymmetrical diene by polymerizing the diene in the presence of [Pd(C 3 H 5 )COD]BF 4 and dicyclohexyl-[1-(2,4,6-trimethylphenyl)imidazol-2-yl]phosphane, Pd(OAc) 2 and triphenylphosphine, or...

Zusammenfassung:A method for the selective synthesis of a tail-to-head, or a head-to-head, or a tail-to-tail telomer from an unsymmetrical diene by polymerizing the diene in the presence of [Pd(C 3 H 5 )COD]BF 4 and dicyclohexyl-[1-(2,4,6-trimethylphenyl)imidazol-2-yl]phosphane, Pd(OAc) 2 and triphenylphosphine, or [Pd(C 3 H 5 )COD]BF 4 and tris(2,4-di-tert-butylphenyl)phosphite in combination with a polar protic alcohol, an acidic polar protic alcohol, a polar aprotic ether, or a non-polar aprotic hydrocarbon is provided.
