C H‐π Interactions in 1‐n‐Butyl‐3‐methylimidazolium

The crystal structure of 1‐n‐butyl‐3‐methylimidazolium tetraphenylborate molten salt (1) shows C H‐π interactions between the hydrogens of the imidazolium cation and the phenyl rings of the tetraphenylborate anion The imidazolium ring is surrounded by three tetraphenylborate anions that are connected with the same cation by C H‐π (phenyl rings) interactions

Silver halide imaging materials Abstract A photosensitive element having a photosensitive medium comprising silver halide in reactive association with an organoborate salt and wherein said medium is selected from: (a) silver halide photographic emulsions comprising a cationic dye and (b) photothermographic media comprising in one or more layers a reducible silver source a reducing

Chemical disinfectants effectively kill pathogenic microorganisms eliminating routes of transmission for infectious diseases Accurate quantification of the active ingredients can help make a more effective use of disinfectants In this study the active ingredients in six different types of chemical disinfectants were systematically quantified with great precision and accuracy using

To answer this question at the strictly molecular level the transfer of a phenyl ring from boron to silver or to lithium in isolated ionic tetraphenylborate complexes was examined by multistage mass spectrometry and quantum chemical calculations in a joint collaboration between Richard O'Hair and Thomas Auth and Konrad Koszinowski from the University of Gttingen

General Chemistry/Types of chemical reactions

Because of the very high reactivities of sodium metal and chlorine gas this reaction releases a tremendous amount of heat and light energy Recall that atoms release energy as they become stable and consider the octet rule when determining why this reaction has such favorable features
