Process for the preparation of acylated secondary alcohol alkoxylates and secondary alcohol alkoxylates

Process for the telomerization of a conjugated diene, wherein the conjugated diene is reacted with a compound containing an active hydrogen atom and having a formula R'&#x2014;H in the presence of a telomerization catalyst based on: (a) a source of group VIII metal, (b) a bidentate ligand wherein the bidentate ligand has the general formula IRRM-R-MRR&#x2003;&#x2003;(I)wherein Mand Mare independently P, As or Sb; R, R, Rand Rindependently represent a monovalent aliphatic group;or R, Rand Mtogether and/or R, Rand Mtogether independently represent an optionally substituted aliphatic cyclic group with at least 5 ring atoms, of which one is the Mor Matom, respectively;R represents a bivalent organic bridging group; and novel bidentate diphosphines which can be used in this process.

Process for the telomerization of a conjugated diene, catalyst and bidentate ligand useful therein

A process for the carbonylation of an ethylenically unsaturated compound with carbon monoxide and a co-reactant. The carbonylation reaction is carried out in the presence of a novel catalyst involving: wherein Rrepresents a bivalent radical that together with the phosphorus atom to which it is attached is an optionally substituted 2-phospha-tricyclo[3.3.1.1{3,7}]- decyl group or a derivative thereof in which one or more of the carbon atoms are replaced by heteroatoms ('2-PA' group); wherein Rand Rindependently represent univalent radicals of up to 20 atoms or jointly form a bivalent radical of up to 20 atoms; and wherein Aand Aindependently represent optionally substituted alkylene groups and R represents an optionally substituted aromatic group; and,
