Oxidative halogenation of cisplatin and carboplatin: synthesis, spectroscopy, and crystal and molecular structures of Pt(IV) prodrugs

12-11-2014 | Timothy C. Johnstone; Sarah M. Alexander; Justin J. Wilson; Stephen J. Lippard, Dalton Transactions, 2014

A series of Pt(iv) prodrugs has been obtained by oxidative halogenation of either cisplatin or carboplatin. Iodobenzene dichloride is a general reagent that cleanly provides prodrugs bearing axial chlorides without the need to prepare intervening Pt(iv) intermediates or handle chlorine gas. ...

Heavy Atom Effect on Magnetic Anisotropy of Matrix-Isolated Monobromine Substituted Septet Trinitrene

11-11-2014 | Eugenii Ya. Misochko; Artem A. Masitov; Alexander V. Akimov; Denis V. Korchagin; Sergei V. Chapyshev, Journal of Physical Chemistry A, 2014

The heavy atom effect on the magnetic anisotropy of septet trinitrenes is reported. Septet 1-bromo-3,5-dichloro-2,4,6-trinitrenobenzene (S-1) was generated in a solid argon matrix by ultraviolet irradiation of 1,3,5-triazido-2-bromo-4,6-dichlorobenzene. This trinitrene displays an electron spin ...

Theoretical Study of Electronic Properties of X-Doped (X = F, Cl, Br, I) VO2 Nanoparticles for Thermochromic Energy-Saving Foils

10-11-2014 | Qinghua Ren; Jinyu Wan; Yanfeng Gao, Journal of Physical Chemistry A, 2014

First-principles density functional theory (DFT) electronic structure calculations were carried out for the model halogen-doped VO2 (M1 phase) to evaluate the effect of halogen (X = F, Cl, Br, I) doping on the band edges. The model structures of X-doped VO2 with X at V site or O site were ...

Dehalogenation of Arenes via SN2 Reactions at Bromine: Competition with Nucleophilic Aromatic Substitution.

07-11-2014 | Scott Gronert; John M. Garver; Charles M. Nichols; Benjamin B. Worker; Veronica M. Bierbaum, The Journal of Organic Chemistry, 2014

The gas-phase reactions of carbon- and nitrogen-centered nucleophiles with polyfluorobromobenzenes were examined in a selected-ion flow tube (SIFT) and modeled computationally at the MP2/6-31+G(d,p)//MP2/6-31+G(d) level. In the gas-phase experiments, rate constants and branching ratios were ...

Kinetics and Mechanism of the Oxidation of Bromide by Periodate in Aqueous Acidic Solution

03-11-2014 | Viktor Szél; György Csekő; Attila K. Horváth, Journal of Physical Chemistry A, 2014

The periodate–bromide reaction has been studied spectrophotometrically mainly in excess of bromide ion, monitoring the formation of the total amount of bromine at 450 nm at acidic buffered conditions and at a constant ionic strength in the presence of a phosphoric acid/dihydrogen phosphate ...

Functional Networks of Organic and Coordination Polymers: Catalysis of Fructose Conversion

03-11-2014 | Lev Bromberg; Xiao Su; T. Alan Hatton, Chemistry of Materials, 2014

The creation of functional porous nanoscale networks with enhanced reactive group accessibility provides rich promise for novel designs of composite materials. We present a straightforward strategy for the preparation of porous polymer/MOF hybrids via polymerization of organic monomers and ...

Photogeneration of Hydrogen from Water by Hybrid Molybdenum Sulfide Clusters Immobilized on Titania

30-10-2014 | David Recatalá, Rosa Llusar, Artem L. Gushchin, Ekaterina A. Kozlova, Yuliya A. Laricheva, Pavel A. Abramov, Maxim N ..., ChemSusChem, 2014

Abstract Two new hybrid molybdenum(IV) Mo3S7 cluster complexes derivatized with diimino ligands have been prepared by replacement of the two bromine atoms of [Mo3S7Br6]2− by a substituted bipyridine ligand to afford heteroleptic molybdenum(IV) Mo3S7Br4(diimino) complexes. Adsorption of the ...

Stable and Low‐Cost Mesoscopic CH3NH3PbI2Br Perovskite Solar Cells by using a Thin Poly(3‐hexylthiophene) Layer as a Hole Transporter

30-10-2014 | Meng Zhang, Miaoqiang Lyu, Hua Yu, Jung‐Ho Yun, Qiong Wang, Lianzhou Wang, Chemistry - A European Journal, 2014

Abstract Mesoscopic perovskite solar cells using stable CH3NH3PbI2Br as a light absorber and low‐cost poly(3‐hexylthiophene) (P3HT) as hole‐transporting layer were fabricated, and a power conversion efficiency of 6.64 % was achieved. The partial substitution of iodine with bromine in the ...

The Platinum Center is a Stronger Nucleophile than the Free Nitrogen Donors in a Dimethylplatinum Complex with a Dipyridylpyridazine Ligand

30-10-2014 | Matthew S. McCready; Richard J. Puddephatt, Organometallics, 2014

The ligand 1,4-di-2-pyridyl-5,6,7,8,9,10-hexahydrocycloocta[d]pyridazine (6-dppd) contains two potential chelate groups, but it coordinates to only one dimethylplatinum group in forming the complex [PtMe2(6-dppd)], 1. Complex 1 contains a free pyridyl and a free pyridazine nitrogen donor, but it ...
