Available in PDF, EPUB and Kindle. Book excerpt: During the last two decades there has been considerable growth in the development of electrospray ionization mass spectrometry (ESI-MS) as a practical method in the study of reaction mechanisms. This method allows the interception and characterization of key intermediates, either as transient species or as protonated/deprotonated forms of neutral species by API-MS. The outstanding features and advantages of ESI-MS make it one of the most suitable tools for the fast screening of intermediates directly from solution, providing hitherto unavailable chemical information to organic chemists. This monograph provides an overview of the mechanisms involved in ESI-MS, the historical perspectives before looking further in-depth at specific reactions and intermediates. Written by researchers in the field, this book is an unique resource for the understanding of this cutting-edge technique.
Download or read book Generation and Observation of Reactive Intermediates in the Gas Phase and Condensed Media written by Matthew Jordan Nava and published by . This book was released on 2017 with total page 446 pages. Available in PDF, EPUB and Kindle. Book excerpt: A molecular beam mass spectrometer (MBMS) has been constructed and upgraded with a laser desorption system. MBMS has allowed for the detection of reactive small molecules including but not limited to P2 from P2A2 (where A = anthracene, C14H10), HCP from PPh3(HCP)A and various dialkylamino phosphinidenes from their corresponding dibenzo-7-phosphanorbornadiene precursors by mass spectrometry. In cases where the desired reactive small molecule was not detected, MBMS has provided valuable information as to the degradation processes which may be occurring and has guided molecular precursor development. Through the use of highly sensitive microwave spectroscopic techniques, it was found that H2S and N2O3 react to form the elusive molecule HSNO in the gas phase. HSNO is believed to be a crucial intermediate in biological signaling. Through isotopic labeling studies, an accurate structure of HSNO could be derived and subsequent degradation of the molecule was explored. The hexacarboxamide cryptand mBDCA-5t-H6 was used as a ligand to prepare mono- and bimetallic iron complexes of the formula [Fe2(mBDCA-5t)]2− and [Fe(mBDCA-5t-H3)]−. Both complexes were observed to react reversibly or irreversibly with CO or NO respectively to afford [(FeEO)-Fe(mBDCA-5t)]2- or [FeEO(mBDCA-5t-H3)]− where E = C or N. Treatment of [(FeNO)·Fe(mBDCA-5t)]2− with excess NO resulted in the formation of [Fe2O(mBDCA-5t)]2-, which could be independently prepared by treatment of [Fe2(mBDCA-5t)]2− with the O-atom transfer reagent N-methylmorpholine N-oxide. The chemistry of peroxide dianion, in the form of the encapsulated complex [O2[subset]mBDCA- 5t-H6]2-, has been explored in nonaqueous media. In particular, [O2[subset]mBDCA-5t-H6]2- was demonstrated to react with CO gas at 40 °C over the course of several hours to furnish the encapsulated carbonate cryptate, [CO3[subset]mBDCA-5t-H6]2-. Through labeling studies, it was confirmed that the carbon of the carbonate was derived from CO. Treatment of [O2[subset]mBDCA-5t-H6]2- with CO2 also affords [CO3[subset]mBDCA-5t-H6]2-, but with concomitant oxidation of the solvent. The oxidation of the solvent was found to proceed through the reactive oxidants −O2COOCO2- and HOOCO2- and sheds light on oxidative processes which may be occurring in lithium-air cells. Exposure of solid Li2O2 to gaseous p-benzoquinone results in the formation of a blue coating on Li2O2. This coating was identified as the quinone radical anion Li[p-C6H4O2], which forms via lithium and electron transfer from Li2O2. This charge and ion transfer process results in the conversion of Li2O2 to LiO2, a long-sought intermediate in the lithium-air community.

Download or read book Gas Phase Metal Reactions written by A. Fontijn and published by Elsevier. This book was released on 2017-05-04 with total page 711 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book brings together, for the first time, all aspects of reactions of metallic species in the gas phase and gives an up-to-date overview of the field. Reactions covered include those of atomic, other free radical and transient neutral species, as well as ions. Experimental and theoretical work is reviewed and the efforts to establish a closer link between these approaches are discussed. The field is mainly approached from a fundamental point-of-view, but the applied problems which have helped stimulate the interest are pointed out and form the major subject of the final chapters. These emphasize the competition between purely gas-phase and gas-surface reactions.
