1,12-Dicarba-closo-dodecaborane (I) was lithiated with n-butyllithium in 1,2-dimethoxyethane and subsequently converted to the C-copper(I) derivative (II) with cuprous chloride. Coupling of (II) with p-iodoanisole (III) in the presence of pyridine furnished the C-arylated compound (IV). This was converted to the C-methoxycarbonyl derivative (V) via formation of the corresponding lithiocarborane, and then treatment with methyl chloroformate. Reduction of the methyl ester group with LiAlH4 produced alcohol (VI). Finally, cleavage of the methyl ether by means of boron tribromide yielded the title compound.
