The visible-light-induced photoredox difunctionalization reactions of styrenes with 1,1,1-trifluoro-2-iodoethane under an oxygen atmosphere in the presence of water give γ-trifluoromethyl alcohols. In this radical reaction, the oxygen atom in the product originates from molecular oxygen, and water is shown...

Difluoroethylsulfonium salt, Ph

Direct Nucleophilic Difluoromethylation of Carbonyl Compounds.

Organic letters

Deng Z, Lin JH, Cai J, Xiao JC.
PMID: 27281283
Org Lett. 2016 Jul 01;18(13):3206-9. doi: 10.1021/acs.orglett.6b01425. Epub 2016 Jun 09.

Phosphonium salt ([Ph3P(+)CF2H] Br(-), DFPB) was found to be an efficient nucleophilic difluoromethylation reagent. Although DFPB is known as a phosphonium ylide precursor, its reaction with carbonyl compounds under traditional "Wittig reaction conditions" did not give the expected Wittig...

[Based on Curing Age of Calcined Coal Gangue Fine Aggregate Mortar of X-Ray Diffraction and Scanning Electron Microscopy Analysis].

Guang pu xue yu guang pu fen xi = Guang pu

Dong ZC, Xia JW, Duan XM, Cao JC.
PMID: 27400535
Guang Pu Xue Yu Guang Pu Fen Xi. 2016 Mar;36(3):842-7.

By using X-ray diffraction (XRD) and environmental scanning electron microscope (SEM) analysis method, we stud- ied the activity of coal gangue fine aggregate under different calcination temperature. In view of the activity of the highest-700 degrees C high temperature...

Uncommon Variant of Type II Monteggia Fracture with Concomitant Distal Humeral Fracture.

Case reports in orthopedics

Matta JF, El Rassi GS, Abd El Nour HG, El Asmar R.

Case Rep Orthop. 2015;2015:374673. doi: 10.1155/2015/374673. Epub 2015 Oct 15.

Monteggia fracture-dislocation, a common injury sustained by pediatric population, is a rare entity in adults. It was first observed by Giovanni Battista Monteggia and later classified by Bado into 4 groups. The term "Monteggia equivalent or variant" was introduced...

Reconstruction of the near-field distribution in an X-ray waveguide array.

Journal of applied crystallography

Zhong Q, Melchior L, Peng J, Huang Q, Wang Z, Salditt T.

J Appl Crystallogr. 2017 May 16;50:701-711. doi: 10.1107/S1600576717004630. eCollection 2017 Jun 01.

Iterative phase retrieval has been used to reconstruct the near-field distribution behind tailored X-ray waveguide arrays, by inversion of the measured far-field pattern recorded under fully coherent conditions. It is thereby shown that multi-waveguide interference can be exploited to...
