All ABSTRACT OF THE TllESIS OF Patrick Jay Green for the Master of Science in Chemistry presented April 16, 1976. Title: Chemistry of Chromium(VI) and Chromium(V) Oxide Fluorides. APPROVEO BY MEMBERS OF THE THESIS CO'"o\l TIEE: y . • Ii . ' I : • • • • • New preparative routes to chromyl fluoride were sought. It was found that chlorine ironofluoride reacts with chromium trioxide and chromyl chlo ride to produce chromyl fluoride. Attempts were ~ade to define a mechan ism for the reaction of ClF and Cr0 in light of by-products observed 3 and previous investigations. Carbonyl fluoride and chromium trioxide react to fom chro·yl fluoride and carbo:i dioxide. A mechanism was also proposed for this react10n. Chromium trioxide 11itl\ l~F6 or WF5 reacts to produce chromyl fluoride and the respective oxide tetrafluoride. 2 Sulfur hexafluoride did not react with Cr03. -

Infobox links nitrogen tribromid is a chemical compound with the NBr3 formula. It is extremely explosive in its purest form, even at 100 degrees Celsius, and was not isolated until 1975. It's deep-red and volatile solid. The drug NBr3 was first prepared by the reaction of bistrimetligrilbramamin (bis (trimethylsil)amin bromide) with bromine monochloride (with trimethylylyl chloride as a by-product) at 87 degrees on the following equations: (Me3Si)2NBr2 BrCl → NBr3 and 2 Me3SiCl, Where Me is He instantly reacts with ammonia in a dichloromethane solution at 87 degrees Celsius to give NBrH2.
