Abstract:

Reaction of Tl27,8-C2B9H11 with RAsX2R CH3, X Br R C6H5, n-C4H9, X Cl in diethyl ether solution produced compounds characterized as 3-R-3-As-1,2-C2B9H11. Spectral data indicate closo-icosahedral structures for these species. Reaction of the synthesized compound with BBr3 afforded 3-Br-3-AS-1,2-C2B9H11. Reaction of CH32AsBr with Tl2C2B9H11 in a 21 ratio afforded CH32As2C2B9H11. Spectral and chemical data suggest a nido 12 vertex structure for this species with one CH32As group terminally bonded to boron. Author
