Platinum(IV) N-heterocyclic carbene complexes: synthesis, characterisation and cytotoxic activity.

22-Jun-2016 | Mathilde Bouché; Georges Dahm; May Wantz; Sylvie Fournel; Thierry Achards; Stephane Bellemin-Laponnaz, Dalton Transactions, 2016

Platinum(II) N-heterocyclic carbene complexes have been oxidized by bromine or iodobenzene dichloride to provide the fully characterised corresponding platinum(IV) NHC complexes. Antiproliferative activities of Pt(IV) NHC complexes were assayed against several cancer cell lines and the results ...

Extension of Structure–Reactivity Correlations for the Hydrogen Abstraction Reaction to the Methyl Radical and Comparison to the Chlorine Atom, Bromine Atom, and Hydroxyl Radical

22-Jun-2016 | Marvin L. Poutsma, Journal of Physical Chemistry A, 2016

Recently, we presented structure–reactivity correlations for the gas-phase rate constants for hydrogen abstraction from sp3-hybridized carbon by three electrophilic radicals (X• + HCR3 → XH + •CR3; X = Cl•, HO•, and Br•); the reaction enthalpy effect was represented by the independent variable ...

Simple magnesium catalyst mediated [gamma]-butyrolactams in desymmetrization of meso-aziridines

21-Jun-2016 | Dan Li; Yijie Wang; Linqing Wang; Jie Wang; Pengxin Wang; Kezhou Wang; Li Lin; Dongsheng Liu; Xianxing Jiang; Dongxu ..., Chemical Communication, 2016

The first α-sp2-carbon of carbonyl compounds attacked catalytic desymmetrization reaction of aziridines is disclosed. A simple in situ generated magnesium catalyst from 3,3′-bromine-8H-BINOL and dibutylmagnesium was employed. It is interesting that the bromine atom on the chiral ligand plays a ...

A Metal-Free Protocol for Aminofunctionalization of Olefins Using TsNBr2

20-Jun-2016 | Kamal Krishna Rajbongshi; Indranirekha Saikia; Loukrakpam Dineshwori Chanu; Subhasish Roy; Prodeep Phukan, The Journal of Organic Chemistry, 2016

N,N-Dibromo-p-toluene sulfonamide (TsNBr2) has been found to be an effective reagent for various aminofunctionalization reactions. This reagent behaves both as an electrophilic bromine source as well as amine to react with olefins under different conditions to yield aminoether, imidazoline, ...

IJMS, Vol. 17, Pages 927: Theoretical Studies on Structures, Properties and Dominant Debromination Pathways for Selected Polybrominated Diphenyl Ethers

16-Jun-2016 | Li, Lingyun ; Hu, Jiwei ; Shi, Xuedan ; Ruan, Wenqian ; Luo, Jin ; Wei, Xionghui, International Journal of Molecular Sciences, 2016

The B3LYP/6-311+G(d)-SDD method, which considers the relativistic effect of bromine, was adopted for the calculations of the selected polybrominated diphenyl ethers (PBDEs) in the present study, in which the B3LYP/6-311+G(d) method was also applied. The calculated values and experimental data for ...

Magnesium Lewis Acid Assisted Oxidative Bromo‐etherification Involving Bromine Transfer from Alkylbromides with Aldehydes via Umpolung of Bromide

15-Jun-2016 | Katsuhiko Moriyama, Chihiro Nishinohara, Hideo Togo, Chemistry - A European Journal, 2016

An oxidative bromo‐etherification involving bromine transfer from alkylbromides upon reacting with aldehydes via the Grignard reaction and the oxidation of bromide was developed to provide substituted tetrahydrofurans in high yields. This reaction, which proceeds through the two types of bromine ...

Insight into the Formation of Highly Strained [1]Ferrocenophanes with Boron in Bridging Position

15-Jun-2016 | Hridaynath Bhattacharjee; Jonathon D. Martell; Elaheh Khozeimeh Sarbisheh; Saeid Sadeh; J. Wilson Quail; Jens Müller, Organometallics, 2016

Four planar-chiral, enantiomerically pure ferrocene dibromides (3R1R2; [(CHR1R2)BrH3C5]2Fe) equipped with two CHR1R2 groups in α position to bromine were synthesized. From the four C2 symmetrical species, two are already known [CHR1R2 = CHMe2 (3MeMe), CHEt2 (3EtEt)] and two are new compounds ...

Synthesis of 6‐Arylpyridin‐3‐ols by Oxidative Rearrangement of (5‐Arylfurfuryl)amines

14-Jun-2016 | Michael C. D. Fürst, Caroline S. Sauer, Takaaki Moriyama, Akio Kamimura, Markus R. Heinrich, European Journal of Organic Chemistry, 2016

The synthesis of 6‐arylpyridin‐3‐ols and their 2,4‐dibrominated analogues has been achieved by the oxidative rearrangement of (5‐arylfurfuryl)amines. The desired arylpyridols were obtained in good to high yields, and the ...

Unusual traits of cis and trans-2,3-dibromo-1,1-dimethylindane on the way from 1,1-dimethylindene to 2-bromo-, 3-bromo-, and 2,3-dibromo-1,1-dimethylindene

10-Jun-2016 | Rudolf Knorr, David S. Stephenson, Ernst Lattke, Petra Böhrer and Jakob Ruhdorfer, Beilstein Journal of Organic Chemistry, 2016

Abstract Do not rely on the widely accepted rule that vicinal, sp3-positioned protons in cyclopentene moieties should always have more positive 3J NMR coupling constants for the cis than for the trans arrangement: Unrecognized exceptions might misguide one to wrong stereochemical assignments ...

Bromine-rich Zinc Bromides: Zn6Br12(18-crown-6)2×(Br2)5, Zn4Br8(18-crown-6)2×(Br2)3, and Zn6Br12(18-crown-6)2×(Br2)2

09-Jun-2016 | David Hausmann; Claus Feldmann, Inorganic Chemistry, 2016

The bromine-rich zinc bromides Zn6Br12(18-crown-6)2×(Br2)5 (1), Zn4Br8(18-crown-6)2×(Br2)3 (2), and Zn6Br12(18-crown-6)2×(Br2)2 (3) are prepared by reaction of ZnBr2, 18-crown-6, and elemental bromine in the ionic liquid [MeBu3N][N(Tf)2] (N(Tf)2 = bis(trifluoromethylsulfonyl)amide). ...
