Triazolyl-phosphole and triazolyl-azaphosphole: synthesis, transition metal complexes and catalytic studies.

Phosphole and azaphosphole derivatives with triazole functionalities, [CH{1,2,3-NCCHC(PPh)}] (L1) and [CH{1,2,3-NC(Ph)C(PPh)}] (L2) were synthesized by reacting [(CH)(1,2,3-NC = CH--Br-CH)] and [(-Br-CH)(1,2,3-NC = CHCH)] with BuLi followed by the addition of dichlorophenylphosphine. The reactions of L1 and L2 with an excess of 30% HO afforded phosphole oxides [CH{1,2,3-NCCHC(P(O)Ph)}] (L1O) and [CH{1,2,3-NC(Ph)C(P(O)Ph)}] (L2O) as white crystalline solids. Stoichiometric reactions of L1 and L2 with [Ru(η--cymene)Cl] in CHCl yielded [RuCl(η--cymene)(L1-κ-)] (1) and [RuCl(η--cymene)(L2-κ-)] (2), respectively.

Solution combustion synthesis of ZnO doped CuO nanocomposite for photocatalytic and sensor applications.

ZnO-doped CuO nanocomposites (CuO-ZnO NPs) of 1, 3, and 5 mol% were prepared by the solution combustion method using ODH as a fuel (Oxlyl-hydrazide) at 500 °C and calcining at 1000 °C for two hours and the Structural, photocatalytic, and electrochemical properties were investigated by experimental and theoretical methods. X-ray diffraction (XRD) patterns revealed a crystallite size (D) range of 25 to 31 nm for pure CuO and 1, 3, and 5 mol% CuO-ZnO NPs. According to calculations, the optical energy band gap (Eg) of the NPs is between 2.

Ni, Pd and Pt pincer complexes of 2-(diphenylphosphanyl)--(2-(diphenyl-phosphanyl)benzyl)benzamide: synthesis, reactivity and catalytic studies.

In this article, the synthesis of bis(phosphine), -PhPCHC(O)N(H)CHCHPPh- (1) (hereafter referred to as "PNHP" and its anionic form as "PNP") and its group 10 metal chemistry and catalytic studies are described. PNHP (1) on reaction with NiCl(DME) and PdCl(COD) afforded pincer complexes, [MCl{(PNP)κ-,,}] (M = Ni, 2; Pd, 3). A similar reaction of 1 with PtCl(COD) yielded a chelate complex, [PtCl{(PNHP)κ-,}] (4), which on further treatment with LiHMDS produced the 1,2-azaphospholene-phosphine complex, [PtCl(Ph){(-P(Ph)CHCONCHCHPPh-)κ-,}] (5) P-C/P-N bond metathesis.

Luminescence Behavior of Cationic and Neutral Cu Complexes of Phosphine and Pyridine Embedded 1,2,3-Triazole.

Synthesis of a potentially polydentate, phosphine and pyridine embedded 1,2,3-triazole, -PhP(CH)C(CH)-1,2,3-N(CH)(Py) () (here onward referred to as "PNN") and its copper complexes are described. Reactions of with CuX yielded mononuclear [Cu{(PNN)-κ-}]X ( - ; X = I, CuBr and CuCl) and dinuclear [Cu{(PNN)-κ-}]X ( X = OTf, X = BF) complexes. Interestingly, the cationic complex [Cu{(PNN)-κ-}]I () in acetonitrile changes into neutral complex [Cu(μ-I)(μ-I)(NCCH){(PNN)-κ(μ-)(μ-)}](), which on addition of dichloromethane reverts back to the cationic form.

Synthesis, structural studies and Hirshfeld surface analysis of 2-[(4-phenyl-1-1,2,3-triazol-1-yl)methyl]pyridin-1-ium hexa-kis-(nitrato-κ ,')thorate(IV).

Reaction of thorium(IV) nitrate with 2-[(4-phenyl-1-1,2,3-triazol-1-yl)meth-yl]pyridine () yielded (H)[Th(NO)] or (CHN)[Th(NO)] (), instead of the expected mixed-ligand complex [Th(NO) ], which was detected in the mass spectrum of . In the structure, the [Th(NO)] anions display an icosa-hedral coordination geometry and are connected by H cations through C-H⋯O hydrogen bonds. The H cations inter-act N-H⋯N hydrogen bonds.
