Recovery of palladium

A process for the carbonylation of allylic alcohols such as nerolidol, farnesol, or their monocyclic analogues with carbon monoxide at a pressure of at least 30 bar in the presence of a polar solvent and a palladium halide catalyst, optionally an alkali metal halide salt, and optionally an alcoholic solvent. The carbonylated product may then be reduced to the corresponding alcohol, which is cyclized in the presence of Lewis or Bronsted acids to afford an ambergris fragrance compound.

Octyl ethers and octadienyl ethers of glucose, sucrose, bisphenol A, 4-substituted-2,2,6,6-tetramethylpiperidines are disclosed. Compositions comprised of a mixture of octyl ethers of glucose and sucrose and those containing octadienyl ethers of sugar acids and ring-opened epoxidized octadienyl ethers are also disclosed as are telomerization processes.
