Reaction of Tl27,8-C2B9H11 with RAsX2 (R = 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 3-C6H5-3-As-1,2-C2B9H11 with BBr3 afforded 3-Br-3-As-1,2-C2B9H11. Reaction of (CH3)2AsBr with Tl2C2B9H11 in a 2:1 ratio afforded [(CH3)2As]2C2B9H 11. Spectral and chemical data suggest a nido 12-vertex structure for this species with one (CH3)2As group terminally bonded to boron.
