Synthesis of Tellurium-Containing σ-Extended Aromatics with Room-Temperature Phosphorescence

A synthesis of tellurium-embedded -extended aromatics from tellurium powder and readily available cyclic diaryliodonium salts has been developed. The versatility of this method has been demonstrated by the synthesis of various functionalized dibenzotellurophenes (DBTe's), a ladder-type -system, and a heterosumanene. These compounds demonstrated good air/moisture stability and high thermal stability. Remarkably, many DBTe's exhibited interesting tunable roomerature phosphorescence (RTP) in the solid state.

First detection of 2,2'-biphenylenediphenylsulfurane and -selenurane [10-M-4(C4), M = S, Se] by low temperature NMR experiments and isolation of the tellurane

Formation of 2,2'-biphenylenediphenylsulfurane and -selenurane was detected in the reactions of 2,2'-biphenylylenephenylchalcogenium compounds with phenyllithium by 1H, 13C, 77Se, and CH-COSY NMR studies at low temperature. Isolation of the tellurane (C) was reported as an example of the tellurane bearing four carbon ligands.
