This monograph comprises contributions from leading scientists on the latest research into the synthesis, structure and bonding of novel selenium and tellurium compounds. It provides insight into mechanistic studies of these compounds and describes coordination chemistry involving selenium and tellurium containing ligands. By varying reaction conditions materials which appear to be intermediates in the trans-metallation process are isolated. Potentially bidentate tellurium ligands having molecular formula RTe(CH2)nTeR,Ln, (R= Ph,(t-Bu). C6H4, n = 5,10) are prepared. Palladium and Platinum complexes containing these ligands are : S.A. Mbogo. Summary This chapter contains sections titled: Introduction Organoselenium Ligands Organotellurium Ligands References Ligand properties of organic selenium and tellurium compounds - Gysling - - PATAI'S Chemistry of Functional Groups - Wiley Online LibraryCited by: However, only sporadically are papers available for the coordination chemistry of carbon-selenium and carbon-tellurium multiple-bond molecules as supporting ligands for transition metals.

Tellurium tetrachloride also forms ionised complexes TeCl 4,L (L = pyridine, pyridine N-oxide), TeCl 4,terpy, and 2TeCl 4,terpy (terpy = 2,2′:6′2″-terpyridyl). Selenium alone yields bis-complexes [SeCl 2,2L″] 2+ 2Cl – with bidentate ligands. Evidence on the various co-ordination numbers of these lenium and tellurium in these compounds. From on a series of conferences dedicated to the chemistry of selenium and tellurium started to be held. Dr. Wolfgang Günther was the first chairman of this series of conferences. 19 At the same time Dr. Günther co-edited an excellent book on the organic chemistry of selenium, 20 and Professors Irgolic and Zingaro published a very. The preparation of compounds containing polyatomic cations of sulphur, selenium and tellurium has been investigated by using oxidising agents such as AsF 5, SbF 5, S F2 and S0 3 • New compounds, containing po 1 ya t om1c.. cat1ons S ea 2+, Se4 2+, TeJn' n+ Te 2+ 4 Ten n+, S2+ 2+ 2+ 16, Sa and S4, andCited by: 7.   Related tetrachelates based on the framework of salen ligands (N,N′-bis(salicylidene)ethylenediamine) have also proved to be powerful and selective catalysts for oxidation reactions. The versatility of porphyrin ligands and related tetrachelates in supporting oxidative systems is illustrated by the chemistry of (TTP)Ti O [TTP = meso (tetra- p -tolyl)porphyrinato], a complex Cited by: 3.
