Veduta V. Stereochemistry of bromine addition to асenaphthylene and its derivatives

Research Object: bromination reaction of acenaphthylene and its derivatives. Research Aim: a study of stereochemistry of bromine addition to acenaphthylene and its derivatives. Methods and devices: organic synthesis, UV, NMR spectroscopy, mass-spectrometry. Theoretical results and the novelty: the nonstereospecificity of bromine addition to a number of acenaphthylene derivatives is established; the dependence of stereochemistry of bromine addition on properties of solvents and substituents is shown, the geometries of neutral and cationic intermediates of acenaphthylene bromination reaction are described. Practical results and their's significance: the kinetic regularities of acenaphthylene derivatives dehydrogenation reaction under an action of DDQ are established, the new derivatives of acenaphthylene and cis-1,2-dibromoacenaphthene are synthesized. Inculcation degree: publications, reports on scientific conferences, usage in research work and pedagogical practice at Research Units and high schools of Ukraine. Effectiveness: is ensured with use of more perfect techniques of synthesis of acenaphtylene and cis-1,2-dibromoacenaphthene derivatives. Spere of Usage: chemistry.
