Description

<jats:title>Abstract</jats:title> <jats:p>A novel synthetic route to a 9-phosphatriptycene was developed by utilizing ortho-lithiation of a triarylphosphine oxide as a key step. Systematic comparisons of the NMR spectra of 9-phosphatriptycene derivatives indicated the large s character of the lone pair orbital or the phosphorus–chalcogen bonds of the 9-phosphatriptycene derivatives.</jats:p>
