CATALYST AND BATTERY COMPONENTS DERIVED FROM CONDENSATION REACTIONS WITH CARBA-CLOSO-DODECABORATE AMINES

Described herein is the fusion of two families of unique carbon-containing molecules that readily disregard the tendency of carbon to form four chemical bonds, namely N-heterocyclic carbenes (NHCs) and carborane anions. Deprotonation of an anionic imidazolium salt with lithium diisopropylamide at room temperature leads to a mixture of lithium complexes of C-2 and C-5 dianionic NHC constitutional isomers as well as a trianionic (C-2, C-5) adduct. Judicious choice of the base and reaction conditions allows for the selective formation of all three stable polyanionic carbenes. In solution, the so-called abnormal C-5 NHC lithium complex slowly isomerizes to the normal C-2 NHC, and the process can be proton catalyzed by the addition of the anionic imidazolium salt. These results indicate that the combination of two unusual forms of carbon atoms can lead to unexpected chemical behavior, and that this strategy paves the way for the development of a broad new generation of NHC ligands for catalysis. 2.

A process for the production of hydrocarbon fuel products from synthesis gas , the process comprising:a. a single reactor system wherein chemical reactions occur in the single reactor system; and,b. a dinuclear metal based catalyst.2. The process of claim 1 , wherein the synthesis gas is contacted in a Fischer-Tropsch reaction with the catalyst.3. The process of claim 2 , wherein the catalyst is a cluster supported on a support comprising a high-surface-area metal oxide claim 2 , and wherein the cluster comprises the active phase for syngas conversion.4. The process of claim 3 , wherein the cluster comprises a syngas conversion agent derived from a list of transition metals comprising cobalt claim 3 , iron claim 3 , nickel claim 3 , copper claim 3 , manganese claim 3 , molybdenum claim 3 , ruthenium claim 3 , and pair-wise combinations of these metals or metal oxides.5. The process of claim 4 , wherein the cluster further comprises at least one metal modifier selected from the elements comprising Groups 1A and 2A of the Periodic Table.6. The process of claim 3 , wherein the support comprises silica claim 3 , alumina claim 3 , titania claim 3 , or a zeolite.7. The process of claim 6 , wherein the support comprises a zeolite which further comprises at least one member selected from the group consisting of the zeolite-based heterogeneous catalyst HZSM-5 claim 6 , Mordenite claim 6 , MCM-22 claim 6 , MCM-41 claim 6 , H-Y-faujasite claim 6 , and H-beta zeolites.8.
