Selective Apical Bromination of Diamantane and Conversion to the Dihydroxy and Dicarboxylic Acid Derivatives.

Abstract New conditions have been found that provide for the selective bromination of diamantane at the 4,9‐positions. Subsequent hydrolysis and Koch–Haaf reaction gave the 4,9‐dihydroxy‐ and 4,9‐dicarboxylic acid derivatives, respectively.
