It was shown that 1-R-2-benzyl-o-carboranes (R=Me, i-Pr, Ph, PhCH2) and other derivatives of o-carborane containing an ArCH2 group in positions 1 and 2 are readily metallized by n-butyllithium, forming the corresponding benzyllithium derivatives, which react with electrophilic reagents like the usual organolithium compounds, permitting the synthesis of various C-substituted 1-o-carboranes.
