The cyclic [N(PiPr2E)2]+ (E = Se, Te) cations: a new class of inorganic ring system.

2006

The two-electron oxidation of [(tmeda)NaN(PiPr2E)2] with iodine produces the cyclic [N(PiPr2E)2]+ (E = Se, Te) cations, which exhibit long E–E bonds in the iodide salts. peerReviewed

Synthesis, Spectroscopic, and Structural Investigation of the Cyclic [N(PR2E)2]+ Cations (E = Se, Te; R = iPr, Ph): the Effect of Anion and R-Group E…

2006

Two-electron oxidation of the [N(PiPr2E)2]- anion with iodine produces the cyclic [N(PiPr2E)2]+ (E = Se, Te) cations, which exhibit long E−E bonds in the iodide salts [N(PiPr2Se)2]I (4) and [N(PiPr2Te)2]I (5). The iodide salts 4 and 5 are converted to the ion-separated salts [N(PiPr2Se)2]SbF6 (6) and [N(PiPr2Te)2]SbF6 (7) upon treatment with AgSbF6. Compounds 4−7 were characterized in solution by multinuclear NMR, vibrational, and UV−visible spectroscopy supported by DFT calculations. A structural comparison of salts 4−7 and [N(PiPr2Te)2]Cl (8) confirms that the long E−E bonds in 4, 5, and 8 can be attributed primarily to the donation of electron density from a lone pair of the halide count…
