Treatment of 5-nitroisocoumarin with aromatic acyl chlorides under Friedel−Crafts conditions gives 3-aryl-5-nitroisocoumarins, rather than the expected 4-acyl-5-nitroisocoumarins. This procedure was optimized for reaction temperature (150 °C), solvent (nitrobenzene), an...

Abstract A survey is given of the nuclear magnetic resonance (NMR) experiments in the manganese perovskites of the form RE 1 − x A x MnO 3 and REMnO 3 + δ (RE = rare earth, A = Ca, Sr, Ba). The 55 Mn, 139 La and 87 Sr spin-echo spectra in the frequency range 5–650 MHz a...

Abstract The title compound was prepared in 29.5% overall yield using a five-step sequence involving two tandem reactions. The current work supports the earlier finding that a strong thermodynamic preference exists for an all-cis relationship across the three contiguous...

Garner, Philip/0000-0002-6503-9550 WOS: 000241030900005 PubMed: 17020278 A new chiral aziridino alcohol ligand for zinc(II)-catalyzed azomethine ylide cycloadditions is described. In the presence of this catalyst, N-arylidene glycine methyl esters react with a variety o...

We observed the in situ growth of a grain during recrystallization in the bulk of a deformed sample. We used the three-dimensional x-ray diffraction microscope located at the European Synchrotron Radiation Facility in Grenoble, France. The results showed a very heteroge...
