“…In contrast, the pyrimidylselenolate complexes, in addition to Se X N chelation, also undergo SeeC bond cleavage [17]. Additional functionalization, as in the present case, leads to the formation of several products formed by the cleavage of CeSe (e.g.…”

“…These reactions with platinum(0) precursors afford mononuclear complexes [12,13] while with palladium(0) species yield binuclear, [Pd 2 (m-ER 0 ) 2 (ER 0 ) 2 (PR 3 ) 2 ] derivatives as isolable products [14e16]. However with internally functionalized ligands, mononuclear palladium complexes are isolated [5,17]. Unlike disulfides/diselenides, reactions of ditellurides with Pd 0 /Pt 0 complexes often yield a mixture of products produced by competitive cleavage of TeeTe and TeeC bonds [18e20].…”

“…[Pt(Te){TeeC 5 H 3 (R) N} 2 (PPh 3 )] [19]. The reactions of dipyridyl diselenides, in general, proceed similar to diphenyl diselenide, but dipyrimidyl diselenide shows different reactivity pattern [17]. In such reactions, besides expected products [M(SeC 5 H 3 N 2 ) 2 (P X P)] a SeeC bond cleaved product, [Pd 3 (m-Se) 2 (P X P) 3 ] 2þ could be isolated [17].…”

“…The 31 P NMR spectrum of complex 2b, 2c, 2d exhibited two 31 P resonance at δ ~ -7 ppm and -11 ppm with different 1 J(Pt-P) coupling constants. The former resonance is deshielded compared to latter one, with 195 Pt-31 P coupling of ~ 2850 Hz indicative of selenolate ligand trans to the phosphine ligand [33][34][35].…”

Reactions of [Pt(SeC5H4N)2(P∩P)] with M(OAc)2.2H2O/MX2 (P∩P = dppm, dppp; M = Zn, Cd, Hg, Cu; X = Cl) resulted various products depend upon the nature of the phosphine. In case of dppm, reaction between [Pt(SeC5H4N)2(dppm)] and M(OAc)2.2H2O/MX2 (M = Zn, Cd, Hg) afforded an exchange product of composition [PtCl2(dppm)]. Similarly, the reaction with 'dppp' analog yielded an adduct [{Pt(SeC5H4N)2(dppp)}MX2] (M = Cd, Hg, Cu; X = Cl, OAc).Whereas, reaction with Zn(OAc)2, on extraction with dichloromethane resulted the product with the loss of one selenium atom of composition [{Pt(C5H4N)(SeC5H4N)(dppp)}ZnCl2]. These complexes were characterized by elemental analyses and NMR ( 1 H, 31 P, 77 Se, 195 Pt) spectroscopy. The molecular structure of [{Pt(C5H4N)(SeC5H4N)(dppp)}ZnCl2] was established by single crystal X-ray diffraction analyses.

Electrochemiluminescence Detection of TNT by Resonance Energy Transfer through the Formation of a TNT–Amine Complex

2,4,6-Trinitrotoluene (TNT) is a widely used nitroaromatic explosive with significant detrimental effects on the environment and human health. Its detection is of great importance. In this study, both electrochemiluminescence (ECL)-based detection of TNT through the formation of a TNT-amine complex and the detection of TNT through electrochemiluminescence resonance energy transfer (ECRET) are developed for the first time. 3-Aminopropyltriethoxysilane (APTES)-modified [Ru(phen)3](2+) (phen=1,10-phenanthroline)-doped silica nanoparticles (RuSiNPs) with uniform sizes of (73±3) nm were synthesized. TNT can interact with APTES-modified RuSiNPs through charge transfer from electron-rich amines in the RuSiNPs to the electron-deficient aromatic ring of TNT to form a red TNT-amine complex. The absorption spectrum of this complex overlaps with the ECL spectrum of the APTES-modified RuSiNPs/triethylamine system. As a result, ECL signals of the APTES-modified RuSiNPs/triethylamine system are turned off in the presence of TNT owing to resonance energy transfer from electrochemically excited RuSiNPs to the TNT-amine complex. This ECRET method has been successfully applied for the sensitive determination of TNT with a linear range from 1×10(-9) to 1×10(-6) M with a fast response time within 1 min. The limit of detection is 0.3 nM. The method exhibits good selectivity towards 2,4-dinitrotoluene, p-nitrotoluene, nitrobenzene, phenol, p-quinone, 8-hydroxyquinoline, p-phenylenediamine, K3[Fe(CN)6], Fe(3+), NO3(-), NO2(-), Cr(3+), Fe(2+), Pb(2+), SO3(2-), formaldehyde, oxalate, proline, and glycine.
