This disclosure relates to a process for making fragrance ingredient or fragrance intermediate which involves isomerizing a starting material comprising a terminal alkene to form a product comprising an internal alkene in the presence of a ruthenium catalyst at a temperature of at least about 120? C.

This describes homogeneous catalysts that are recoverable from solution by being phase selective and through host-guest interactions. An example of a method includes separating a water soluble N-heterocyclic carbene homogeneous catalyst from a solution by: (a) forming a host-guest compound between the catalyst and an inclusion compound in the solution; and (b) isolating the host-guest compound from the solution.

A flame retardant itaconic acid-based compound, a process for forming a flame retardant polymer, and an article of manufacture comprising a material that contains a flame retardant itaconic acid-based polymer are disclosed. The flame retardant itaconic acid-based compound has variable moieties, which include methylene bridge groups, carbonyl groups, vinyl groups, functionalized groups, phenyl-substituted flame retardant groups, and/or functionalized flame retardant groups. The process for forming the flame retardant polymer includes forming a phosphorus-based flame retardant molecule, forming an itaconic acid derivative, chemically reacting the phosphorus-based flame retardant molecule and the itaconic acid derivative to form a flame retardant itaconic acid-based compound, and incorporating the itaconic acid-based flame retardant compound into a polymer to form the flame retardant polymer.
