Chemistry of Decaborane-Phosphorus Compounds. V. Synthesis and Phosphination of Bromocarboranes

摘要

Aluminum halide catalyzed bromination of carborane and neocarborane resulted in a stepwise substitution with tri bromocarborane and dibromoneocarborane respectively, as the ultimate products. Further halogenation was achieved with chlorine to give B10H2Br3Cl5C2H2, B10Br2Cl8C2H2, and neo-B10Br2Cl8C2H2. Some reactions of the bromocarboranes including the preparation of phosphorus derivatives are described. (Author)
