Freshly prepared catalyst was used in all the hydrogenations.
The composition of polybutadiene-containing block copolymers can be changed via hydrogenation of the carbon-carbon double bonds of the polybutadiene, resulting in materials with improved resistance towards thermal and oxidative degradation [9-11].
Bergens and his graduate student Jeremy John hypothesized that the complex was falling apart at the higher temperatures that are required to get amide hydrogenations to work.
In 24 hours, each molecule of the new catalyst system can achieve up to 7,600 amide hydrogenations under relatively mild conditions; the previous record was only about a hundred hydrogenations in 48 hours.
In heterogeneous catalysis, catalyst systems containing noble metals (Pd, Pt, Ru) supported over silica allow one to work under gentle conditions: for example, hydrogenations at 40[degrees]C under 10 bar of hydrogen.
This will also free additional capacity in our existing developmental plants, in particular where cryogenic reactions and hydrogenations are part of the process," said Michael Major.

One strategy to achieving the conversion of polyols to [alpha], [omega]-diols is the use of an (iterative) cascade of acid catalyzed dehydrations and transition metal catalyzed hydrogenations of the alkenes and carbonyls and/or hydrogenolysis of the oxygen-carbon bonds in the oxacycles resulting from the dehydration and condensation steps (Figure 1).
He has lately focused on Pd-catalyzed hydrogenations, involving N-ligands and N-heterocyclic carbenes, as well as catalysis involving aggregates (micelles and vesicles) of metallo-amphiphiles.
