Abstract

A series of asymmetrically substituted sulfonium derivatives of nido-carborane [9-R(Me)S-nido-7,8-C₂B₉H₁₁] (R = Et, Pr, Bu, Bn, CH [double bond, length as m-dash] CH₂, CH₂CHCH₂, CH₂C [triple bond, length as m-dash] CH, CHCCH₂) were prepared by alkylation of the 9-methylthio-nido-7,8-carborane. The synthesized compounds are the first examples of diastereomers combining nido-carborane and sulfonium chiral centers.
