标题 :Method for the synthesis of tris(ortho-carboranyl)borane
发明人：Martin Caleb; AKRAM MANJUR OYASIM
权利人:UNIV BAYLOR
摘要:The described process synthesizes a halide-free single-site borane compound product tris(ortho-carboranyl)borane, or BoCb3. BoCb3 has Lewis superacid properties. The compounds, BoCb3, are thermally stable, and not reactive towards oxygen, but are sensitive to water. The characteristic high fluoride ion affinity is further translated to the catalytic C—F bond activation reactions of the unactivated alkyl fluorides towards the reduction and C—C bond forming reactions with silanes, and Fridel-Crafts type reactions with arenes. The potential of the synthesized Lewis acid as a catalysis is anticipated.

摘要:Preparation and use of tetra-C-alkyl cobalt dicarbollide for extraction of cesium and strontium into hydrocarbon solvents. Tetra-C-alkyl derivatives of cobalt dicarbollide, Co(C 2 R 2 B 9 H 9 ) 2 - (CoB 2 R 4 - ; R=CH 3 and C 6 H 13 ) are demonstrated to be significant cesium and strontium extractants from acidic and alkaline solutions into non-toxic organic solvent systems. Extractions using mesitylene and diethylbenzene are compared to those with nitrobenzene as the organic phase. CoB 2 -hexyl 4 - in diethylbenzene shows improved selectivity (10 4 ) for Cs over Na in acidic solution. In dilute alkaline solution, CoB 2 -hexyl 4 - extracts Cs less efficiently, but more effectively removes Sr from higher base concentrations. A general synthesis of tetra-C-alkyl cobalt dicarbollides is described.

标题 :Reactive secondary boranes and methods for synthesis thereof
发明人：Martin Caleb; AKRAM MANJUR
权利人:UNIV BAYLOR
摘要:A secondary borane featuring two ortho-carborane substituents [HBoCb2, oCb=ortho-carborane] is useful as a powerful hydroboration reagent. The Lewis superacid, bis(1-methyl-ortho-carboranyl)borane, is rapidly accessed in two steps. It is a very effective hydroboration reagent capable of the hydroboration of alkenes, alkynes, cyclopropanes, and allenes. The large steric profile prevents double hydroboration of alkynes and promotes regioselectivity in allenes. The compound is a Lewis superacidic secondary borane and effective neutral hydroboration reagent.
