Chemistry. 2013 Jan 02;19(1):109-16. doi: 10.1002/chem.201203260. Epub 2012 Nov 23.

The room-temperature ionic liquid (RT-IL) [C(CH(3))(3)](+)[Al(2)Br(7)](-) (m.p. 2 °C) was generated by bromide abstraction from tert-butyl bromide with the Lewis acid aluminum bromide in the absence of solvent. The crystal structure of the tert-butyl cation salt was determined by...

Anal Chem. 2015 Mar 03;87(5):2623-30. doi: 10.1021/ac504692m. Epub 2015 Feb 23.

This work introduces a conceptually new approach of measuring pH of mixed-solvent liquid chromatography (LC) mobile phases. Mobile phase pH is very important in LC, but its correct measurement is not straightforward, and all commonly used approaches have deficiencies....

PMID: 25803574
Dalton Trans. 2015 Apr 28;44(16):7489-99. doi: 10.1039/c4dt02822h.

The possibility of obtaining frustrated Lewis pairs (FLPs) suitable for H2-activation based on the Lewis acid B(Ohfip)3 1 (Ohfip = OC(H)(CF3)2) was investigated. In this context, the crystal structure of 1 as well as the crystal structure of the...

A new Li salt with views to success in electrolytes is synthesized in excellent yields from lithium borohydride with excess 2,2,2-trifluorethanol (HOTfe) in toluene and at least two equivalents of 1,2-dimethoxyethane (DME). The salt Li[B(OTfe)4 ] is obtained in...

Hexaazatrinaphthylenes with different twists.

Chemistry (Weinheim an der Bergstrasse, Germany)

Chemistry. 2014 Feb 03;20(6):1525-8. doi: 10.1002/chem.201304071. Epub 2013 Dec 09.

A synthetic strategy that allows the induction of twist angles of different sizes in 5,6,11,12,17,18-hexaazatrinaphthylene (HATNA) chromophores is reported. The different twist angles are accompanied by measurable changes in the emission and electrochemical characteristics of HATNA.

Radioguided Parathyroidectomy with Portable Mini Gamma-Camera for the Treatment of Primary Hyperparathyroidism.

Background. A proper localisation of pathological parathyroid glands is essential for a minimally invasive approach in the surgical treatment of primary hyperparathyroidism (PHP). The recent introduction of portable mini gamma-cameras (pMGCs) enabled intraoperative scintigraphic scanning. The aim of our...

The synergistic Ag(+) /X2 system (X=Cl, Br, I) is a very strong, but ill-defined oxidant-more powerful than X2 or Ag(+) alone. Intermediates for its action may include [Agm (X2 )n ](m+) complexes. Here, we report on an unexpectedly variable...
