By using Pd(TFA)2/PCy3 as a catalyst, broad range of aromatic carboxylic acids, including heteroaromatic efficiently underwent decarboxylative coupling with an array polyfluoroarenes in the presence stoichiometric amount silver salts to generate biaryls. Silver were adjusted reactivity acids suppress protodecarboxylation and therefore improve cross-couplings. It was established that palladium complex containing PCy3 ligand capable catalyzing decarboxylation electron-rich promoted both...

Abstract A domain wall, as a device, can bring about revolution in developing manipulation of semiconductor heterostructures devices at the atom scale. However, it is challenge for these new to control wall motion through insulator-metal transition correlated-electron materials. To fully understand and harness this motion, requires visualization dynamics real space. Here, VO 2 phase was observed directly by situ TEM Experimental results depict scale evolution morphologies exact positions...

A simple chiral binuclear titanium complex ((S)-Ti2L3Na4) was first prepared and served as an excellent sensor for discriminating a variety of ammoniums by 1H NMR. In the presence trifluoroacetic acid, in-situ-generated varied amines can be effectively resolved (S)-Ti2L3Na4. The different binding forces between (S)-Ti2L3Na4 two enantiomers analytes generate shielding effects on enantiomers, resulting in split distinguishable chemical shift.
