Nonlinear optical properties of new organotellurium compounds containing azomethine and azo groups under CW laser illumination

Synthesis and characterization of some new organotellurium compounds based on quinoline

“…The IR spectra of compounds 1-10 display weak bands in the region between 3051 and 3076 cm -1 , however at higher frequency, are assigned to C-H stretching vibrations of aromatic rings of quinolone [12,13]. Also, the IR spectra of compounds 1-10 show two bands in the range 1527-1583 and 1521-1436 cm -1 can be attributed to asymmetrical and symmetrical stretching of aromatic C=C, respectively [2,[11][12][13]. Furthermore, several variable bands between 611 and 806 cm -1 range can be assigned to aromatic bending of C-H. A weak band was appeared in IR spectra of compounds 2-7 at range 457-466 cm -1 may be attributed to Te-C stretching [14].…”

Synthesis, Characterization, Ligand Properties and Theoretical Study of Some New Organic Tellurium Compounds Driven From Indole.

“…The IR spectra of compounds (1-10) show week bands in the range 455-588 cm-1 due to ʋ(Te-C) vibration. 11 Comparison IR spectra of complexes 8, 9 and 10 with compound 5, a high frequency shift ( 9-37cm -1 ) was appeared can be attributed to coordinate of nitrogen atoms of compound 5 with palladium, platinum and rhodium ions respectively. Also, IR spectra of complexes 8, 9 and 10 show a weak band at 460, 435and 455 cm -1 respectively with low frequency which indicate to coordinate tellurium atom of compound 5 with palladium, platinum and rhodium ions respectively.…”

“…Large numbers of organotellurium compounds were prepared by transmetallation reaction of aromatic organomercuric chloride with TeBr 4 in dioxane in which the products depend on the mole ratio of Ar-HgCl to TeBr 4 if 1:1 gave Ar-TeBr 3 and 2:1 afford Ar 2 TeBr 2 which on reduction gave symmetrical tellurides. 10,11 In the present work, a series of new organotellurium compounds based on indole will be prepared via transmetallation reaction of 3-(indolyl) mercuric chloride with tellurium tetrabromide in 1:1 and 1:2 mole ratio, respectively. Furthermore, the ligand properties of bis [3-(indolyl)] telluride will be carried out with K 2 PtCl 4 , Na 2 PdCl 4 and RhCl 3 .3H 2 O.…”
