Synthesis and redox properties of a para-borylated phenylxanthenium cation

abstract

• Reaction of 4-(lithiophenyl)dimesitylborane with xanthone followed by reaction of the resulting alcohol with HBF4affords the cation 1-dimesitylboron-4-(9-xanthylium)-phenylene [1]+as a tetrafluoroborate salt. This salt has been fully characterized and its crystal structure determined. Cation [1]+can be reduced to produce a persistent radical that has been studied by EPR and whose reaction with dioxygen affords a peroxo derivative. 2010 - IOS Press and the authors.
