Provided is a process for the preparation of certain 1,4-bicyclo[2.2.2]octane derivatives. The new synthetic procedure involves treating 1,4-dimethylene cyclohexane with an oxidizing agent in the presence of a transition metal catalyst to afford an oxo-substituted bicyclo[2.2.2]octane species. This intermediate structure can then be further derivatized. The processes of this disclosure thus affords a novel and simplified means for the commercial production of a wide variety of bicyclo[2.2.2]octane derivatives.

The invention provides (meth)acrylic oligomers prepared from C1-C20 alkyl and C5-C20 cycloalkyl (meth)acrylates, wherein said oligomers have a Mn of about 300 g/mole to about 3,000 g/mole; a Mw of about 700 g/mole to about 6,000 g/mole; a Mz of about 900 g/mole to about 10,000 g/mole. The oligomers may have a Yellowness Index, according to ASTM E313 of less than 2. The oligomers of the invention are useful as tackifiers in adhesive compositions, but also are believed to be useful also in general polymer modification as plasticizers, leveling agents, viscosity reducers (i.e., rheology modifiers), and for increasing solids content in solvent-borne applications of all types with little detrimental impact on viscosity. The invention also provides adhesive compositions and laminate articles coated on at least one side with the adhesive compositions of the invention.

Disclosed is a process for performing a reductive amination of a first functional group in an organic feed substrate, which feed substrate comprises at least one further functional group containing a halogen atom, in the presence of hydrogen, a nitrogen-containing compound, and a catalyst, wherein the presence of the nitrogen-containing compound, expressed in a molar ratio relative to the first functional group in the organic feed substrate, at least during the reaction as long as the conversion of the organic feed substrate has not yet reached 80%, is maintained below a level of 1.3. Further disclosed is a composition of the invention comprising at least 98.0% wt of 2-chloro-benzyl-dimethylamine, at most 0.60% wt of the meso-o-Cl-BDMA dimer and at least 1 ppm wt of the (+/&#x2212;)-o-Cl-BDMA dimer and any use therefor.

Disclosed is a method of making and using a titania supported palladium catalyst for the single step synthesis of 2-ethylhexanal from a feed of n-butyraldehyde. This titania supported palladium catalyst demonstrates high n-butyraldehyde conversion but also produces 2-ethylhexanal in an appreciable yield with maintained activity between runs. This method provides a single step synthesis of 2-ethylhexanal from n-butyraldehyde with a catalyst that can be regenerated that provides cleaner downstream separations relative to the traditional caustic route.
