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

Abstract 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.
