The research focuses on the synthesis and characterization of weakly coordinating anion salts of a new, stable carbocationic reagent, the dibenzosuberenyl (dibenzotropylium) ion. The purpose of the study was to develop alternative carbocationic species as carbanion abstracting reagents and to investigate their potential as alkylating agents. The conclusions drawn from the study indicate that the DBS+ carbocation is planar with significant delocalization of the positive charge over part of the seven-membered ring and is an efficient carbanion abstractor, activating metallocene catalyst precursors like Cp2ZrMe2. The efficacy of DBS+ was found to be comparable to that of the well-known trityl carbocation, Ph3C+. The research also established that DBS+ does not initiate carbocationic polymerization of isobutene directly in dichloromethane but rather through reaction with trace amounts of water to generate protons.
The research focused on determining the activation energy for the ring-closure reaction of ground state triplet trimethylenemethane (I) to methylenecyclopropane. The purpose was to measure this energy by monitoring the rate of disappearance of the electron spin resonance spectrum over a specific temperature range in frozen solid matrices, using 3-methylenecyclobutanone and methylenecyclopropane as precursors to trimethylenemethane. The study concluded that the activation energy for the ring-closure was significantly lower than the theoretical estimates, with a value of 7 kcal/mole, contrasting with the approximate 20 kcal/mole barrier suggested by theoretical models. The chemicals used in the process included 3-methylenecyclobutanone, methylenecyclopropane, isobutylene, and various solvents such as methylcyclohexane, perfluoromethylcyclohexane, decalin, and tetrahydrofuran for the matrix solutions. The research also involved the synthesis and use of fully deuterated methylenecyclopropane-da to investigate the possibility of a tunneling mechanism in the ring-closure reaction.
The research investigates the intermolecular fluorine atom abstraction from fluorocarbons, including saturated perfluorocarbons, by the compound (MeCsH&U(t-Bu). The study reports that this compound can efficiently abstract fluorine atoms under mild conditions in hydrocarbon solvents. Key chemicals involved in the research include hexafluorobenzene, which reacts with (MeCsH&U(t-Bu) to produce uranium (IV) fluoride and various organic products such as CsFsH, CsFs(t-Bu), isobutane, and isobutene. Other fluorocarbons like benzotrifluoride and perfluoromethylcyclohexane were also used to explore the scope of the C-F bond activation process. The reactions were monitored using techniques like NMR spectroscopy, GC, and GC-MS to identify and quantify the products. The study proposes a radical cage mechanism for these reactions, suggesting that the formation of a U-F bond and subsequent C-C or C-H bond formations drive the process.
