Novel 9-phosphatriptycenes were synthesized by utilizing ortho-lithiation of a triarylphosphine oxide as a key step. The structural analysis of the 9-phosphatriptycene oxide revealed its highly distorted structure around the phosphorus atom, which...
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...

A novel bowl-type triarylgermyl group, tris(2,2",6,6"-tetramethyl[1,1':3',l"-terphenyl-5'-yl]germyl(denoted as TRMG), was designed, and a germanol and its derivatives bearing this framework were synthesized. X-ray crystallographic analysis of TRMG...
