Synthesis and characterization of some aliphatic oxohalochromates, investigation of oxidation reactions of various organic compounds in different media and bromination of some aromatic compounds

SYNTHESIS AND CHARACTERIZATION OF SOME ALIPHATICOXOHALOCHROMATES, INVESTIGATION OF OXIDATION REACTIONSOF VARIOUS ORGANIC COMPOUNDS IN DIFFERENT MEDIA ANDBROMINATION OF SOME AROMATIC COMPOUNDS(M.Sc. Thesis)Ebru ÜSTÜNGAZ UNIVERSITYINSTITUTE OF SCIENCE AND TECHNOLOGYHaziran 2006ABSTRACTIn this study new reagents 1,1,3,3-tetramethylguanidiniumfluorochromate (TMGFC), 1,1,3,3-tetramethylguanidiniumchlorochromate (TMGCC) and 1,1,3,3-tetramethylguanidiniumbromochromate (TMGBC) were synthesized and their structures weredetermined. The physical properties such as melting point, solubility,pH and conductivity were examined. The new oxidative systemsnamely; TMGFC/Alümina, TMGCC/Alümina, TMGBC/Alümina andTMGDC/Alümina were prepared. The oxidation and deoximationreactions of various organic compounds were carried out by thesereagents in solution, solvent-free medium and under microwaveirradiation respectively. Some aromatic compounds were brominatedby using 1,1,3,3-tetramethylguanidinium bromochromate.Science Code : 201.1.112Key Words : Halochromates, Oxidation, Deoximation,Bromination, MicrowavePage Number : 102Adviser : Prof. Dr. Beytiye ÖZGÜN
