Methyl 8-oxo-2-phenyl-1-oxaspiro[4.5]deca-2,6,9-triene-3-carboxylate

open access: yesIUCrData, 2016
The title compound, C17H14O4, is a 5/6 spiro-ring fused system, where the five- and six-membered rings are inclined to one another by 89.79 (5)° at the spiro-carbon. In the crystal, non-classical C—H ... O hydrogen bonds form inversion dimers and connect

The growth of interest for astronomical X-ray polarimetry

open access: yes, 2018
Astronomical X-ray polarimetry was first explored in the end of the 60's by pioneering rocket instruments. The craze arising from the first discoveries on stellar and supernova remnant X-ray polarization led to the addition of X-ray polarimeters on-board

X – RAY DIFFRACTION ANALYSIS OF SLUDGE AND DUST PRODUCED IN STEELWORKS

open access: yesActa Metallurgica Slovaca, 2013
Before handling, storage, disposal, these wastes need to be analyzed. In many cases, it is not enough to know only their chemical composition, but it is necessary to determine their mineralogical composition, or to know exactly what is their ...

Sequential decarboxylative azide–alkyne cycloaddition and dehydrogenative coupling reactions: one-pot synthesis of polycyclic fused triazoles

open access: yesBeilstein Journal of Organic Chemistry, 2014
Herein, we describe a one-pot protocol for the synthesis of a novel series of polycyclic triazole derivatives. Transition metal-catalyzed decarboxylative CuAAC and dehydrogenative cross coupling reactions are combined in a single flask and achieved good ...
