摘要:
Process for the telomerization of dienesThe present invention relates to a process for the telomerization of dienes, according to which the diene is reacted with a compound containing an active hydrogen atom in the presence of a palladium compound, a water-soluble phosphine ligand and a base, the water-soluble ligand being a bidentate ligand having the following formula I ##STR1## in which R is identical or different and is phenyl, C.sub.1 -C.sub.12 -alkyl or C.sub.3 -C.sub.10 -cycloalkyl, which may be unsubstituted or substituted by one or more radicals R',R' is identical or different and is SO.sub.3.sup.- M.sup.+, --NMe.sub.3.sup.+ or --COO.sup.- M.sup.+,n is an integer from 1 to 6, in each case based on a naphthyl backbone, andM is H, Na, K, Cs or R".sub.4 N.sup.+ where R" is identical or different and is H, C.sub.1 -C.sub.12 -alkyl or C.sub.1 -C.sub.10 -cycloalkyl.
