Abstract
Pentaalkyl-6-bromo-2,3,4,5-tetracarba-nido-hexaboranes(6) (3-carb-Br and 4-cab-Br) react with lithium-diphenylphosphide to give the 6-diphenylphosphino substituted carboranes 3-carb-PPh2 and 4-carb-PPh2. 3-carb-PPh2 can be oxidized to give the respective oxide, sulfide and selenide. Treatment of 4-carb-PPh2 with an excess of methyl iodide cleaves the P-B bond and 4-carb-I is formed together with [Me2Ph2P]+I. 4-carb-PPh2 reacts with borane in tetrahydrofuran (BH3-THF/THF) or W(CO)5-THF/THF to give the BH3 and W(CO)5 complexes. All products were characterized by 1H, 11B, 13C and 31P NMR spectroscopy.Keywords
