Abstract:
A series of mono, bi and tricarbocyclic compounds, most of which have olefinic unsaturation in the ring, which may or may not have substituents thereon. While the bi and tricyclic rings may be unsubstituted, these compounds which have olefinic unsaturation, particularly multiple olefinic unsaturation, are polymerizable and copolymerizable in known polymerization systems. They are particularly good crosslinking agents. These compounds are further useful in the sense that they can be cleaved oxidatively, to corresponding carboxylic acids, aldehydes and/or alcohols which have known utility in the plasticizer and detergent arts. The compounds which do not have olefinic unsaturation can also be oxidatively cleaved to produce oxygenated, e.g., acid, alcohol or aldehyde, compounds having known utility.
Abstract:
THEREIS PROVIDED AS A NEW COMPOUND NONADECAPENTA1,6,9,13,18-ENE-10-METHYL CARBOXYLATE. THIS IS PREPARED BY REACTION OF METHYL METHACRYLATE WITH BUTADIENE IN THE PRESENCE OF ZERO-VALENT NICKEL OR BY REACTION OF BUTADIENE WITH UNDERCATRI-1,5,10-EE-2-METHYL CARBOXYLATE FORMED AS AN INTERMEDIATE WHICH MAY BE ISOLATED OR NOT AS DISIRED.
Abstract:
A PROCESS FOR THE CATALYTIC DIMERISATION OF 1,3-DIOLEFINES IS DISCLOSED. PREFERRED DIOLEFINES ARE BUTADIENE, ISOPRENE AND PIPERYLENE. THE CATALYSTS USED ARE ONES FORMED BY MIXING A REDUCIBLE NICKEL COMPOUND AND A METAL HAVING A REDUCING ACTION WITH RESPECT TO THE REDUCIBLE NICKEL COMPOUND OR A HALOGEN-FREE ORGANOMETALLIC COMPOUND, OF WHICH METAL ALKYLS, METAL ARYLS OR METAL HYDRIDES ARE EXAMPLES, AND AN ELECTRON DONOR. THEY MAY ALSO BE FORMED BY MIXING A NICKEL COMPLEX COMPOUND WHICH CONTAINS O-VALENT NICKEL WITH AN ELECTRON DONOR. THE ELECTRON DONOR MAY BE AN ESTER OF A PHOSPHOROUS ACID OR A DIOLEFINE. THE PROCESS IS CARRIED OUT WITH INCOMPLETE CONVERSION OF THE 1,3-DIOLEFINE.

Abstract:
ZERO-VALENT COMPLEXES OF GROUP VIII METALS, OXYGEN AND AN ELECTRON DONOR SUCH AS, FOR EXAMPLE, A GROUP V METAL TRIVALENT COMPOUND, E.G., TRIPHENYL PHOSPHINE; PRODUCTION OF SUCH ZERO-VALENT COMPLEXES BY REACTING A ZEROVALENT COMPOUND OF A GROUP VIII METAL AND AN ELECTRON DONOR WITH MOLECULAR OXYGEN PREFERABLY AT A TEMPERATURE OF ABOUT - 100 TO ABOUT 75*C. THESE COMPLEXES CAN BE USED AS OXYGEN TRANSFER AGENTS AND FOR THE PREPARATION OF FINELY DIVIDED, HIGHLY ACTIVE METALS OF SUB-GROUP VIII OF THE PERIODIC TABLE.
Abstract:
Bicyclo-(3,3,0)-octene-(2) is prepared with quantitative conversion and in high yields at substantially room temperature and high reaction rate with the use of a catalytic mixture of nickel compounds and aluminum compounds. The resulting bicyclooctene is a valuable monomer for the production of a high molecular weight polyolefin or a starting material for alicyclic dicarboxylic acids.
Abstract:
PROCESS OF CYCLOCO-OLIGOMERIZATION OF A CONJUGATED DIOLEFIN, SUCH AS BUTADIENE OR A SUBSTITUTED BUTADIENE, WITH A DIFFERENT CYCLIC UNSATURATED HYDROCARBON, WHICH IS AN ACETYLENE AND/OR A NON-CONJUGATED OLEFIN, PREFERABLY A MONOOLEFIN, TO PRODUCE MULTICYCLIC PRODUCTS HAVING OLEFINIC UNSATURATION IN AT LEAST ONE OF THE RINGS. THESE PRODUCTS ARE MADE BY REACTING THE ABOVE-MENTIONED REACTANTS TOGETHER IN CONTACT WITH A CARBONYL-FREE, O-VALENT NICKEL COMPOUND CATALYST. MANY OF THE NEW PRODUCTS FORMED BY THIS PROCESS ARE DESCRIBED, CHARACTERIZED AND CLAIMED.
