Emerging trends in organotellurolate chemistry derived from platinoids

Abstract

This perspective begins with the discussion of various basic synthetic approaches applied for the synthesis of several organotellurium ligands, their chemistry derived from platinum group metals, and the reactivity difference among them.

Experimental and computational investigation on the formation pathway of [RuCl2(CO)2(ERR′)2] (E = S, Se, Te; R, R′ = Me, Ph) from [RuCl2(CO)3]2 and ERR′

“…During the last three decades these complexes have attracted more attention, which is centered on the ligand chemistry of seleno- and telluroethers in addition to thioethers (for more recent reviews, see ref. 5). Hieber and John 6 explored already in 1970s the isomerism of [RuCl 2 (CO) 2 (ERR′) 2 ] (E = S, Se, Te; R, R′ = a number of alkyl or aryl groups) by recording the dipole moments, IR spectra, and 1 H NMR spectra of the complexes formed in different reactions.…”

Metal-metalloid bond containing complexes of the bulky organotellurium ligand: applications in catalysis of C–O coupling and aldehyde to amide transformation reactions

“…16,17 Interestingly, unlike organosulfur derivatives, the NMR activity of the nucleus of 125 Te enables chemists to study the organotellurium compounds using 125 Te NMR spectroscopic techniques. Despite this advantageous feature, 16,17 the chemistry of organotellurium compounds has remained neglected for many years, probably owing to the belief that they have malodorous and unstable character, 18 strong reactivity, 19 and air as well as light sensitivity. 19 Though such properties are shown by some of the organotellurium compounds, it is not true for all Te-containing compounds and it is not less interesting at all to explore them in the field of catalyst development.…”

Bis(2-pyridyl)ditellane as a precursor to CoII, CuI and CuII complex formation: structural characterization and photocatalytic studies

“…Also, for C–E (E = Te, Se, S) the bond energies are substantially lower for tellurium. 1,9 Therefore, the formation of several tellurium compounds can result from the Te–Te or Te–C bond cleavage. 10–14…”

“…Also, for C-E (E = Te, Se, S) the bond energies are substantially lower for tellurium. 1,9 Therefore, the formation of several tellurium compounds can result from the Te-Te or Te-C bond cleavage. [10][11][12][13][14] Recently, our research group reported the synthesis and structural characterization of exotic pyridyltellurolate clusters, zwitterionic and coordination compounds using bis(2-pyridyl) ditellane (Fig.…”
