Electron-Acceptor Behavior of 2,4,7,9-Tetracarba-nido-dodecaborane(12) with Group 1 and Group 2 Metals: Syntheses and Crystal Structures of (THF)4Li(SiMe3)4C4B8H9 and (THF)2Mg(SiMe3)4C4B8H8
The room-temp. reaction between a THF soln. of 2,4,7,9-tetracarba-nido-dodecaborane(12) (SiMe3)4C4B8H8 and finely cut excess lithium or magnesium metal, in the absence of naphthalene and arom. solvents, produced either (THF)4Li(SiMe3)4C4B8H9 (1) as an EPR-silent transparent cryst. solid in 41\% yield or (THF)2Mg(SiMe3)4C4B8H8 (2) as an off-white cryst. solid in 88\% yield. While the solid-state structure of 1 showed a single anionic (SiMe3)4C4B8H9- unit that was well-sepd. from a discrete Li(THF)4+ cation, the structure of 2 is that of a novel magnesacarborane in which the carborane cage incorporates both electron-precise and electron-deficient carbon and boron atoms. on SciFinder(R)
