Synthesis of Triphosphatruxene via Sextuple Aromatic Nucleophilic Substitution and Simple Isolation of Stereoisomers

Synthesis of Triphosphatruxene via Sextuple Aromatic Nucleophilic Substitution and Simple Isolation of Stereoisomers

The phosphorus analog of truxene, triphosphatruxene, was effectively synthesized by a sextuple aromatic nucleophilic substitution reaction with phenylphosphine. The vacuum sublimation process completely converted the mixture of stereoisomers into the thermodynamically unpreferred syn-isomer.
