Dimethylsulfoxide Acyl and aryl halides, boron compounds, bromomethane, nitrogen dioxide, magnesium perchlorate, periodic acid, silver difluoride, sodium hydride, sulfur trioxide... 

Trifluoromethaneseleninyl chloride (3) can be prepared by the reaction of trifluoromethane-sclcnenyl chloride with ozone whereas nitrogen dioxide transforms the initially formed acid choride to the anhydride (CF3Se0)20.316 Trifluoromethaneselenenic acid chloride and bromide are oxidized with hypofluorous acid in acetonitrile to the corresponding seleninyl halides 3 and 4, respectively.204 When an excess of hypofluorous acid is employed, the selenenyl halides and trifluoromethaneseleninic acid (5) are oxidized to the anhydride 6.304... 

Nitrosyl chloride can be obtained by direct combination of chlorine with nitric oxide, by the reaction of NOHSO4 or NaNOj with HCl, or as a by-product in the preparation of KNOs from KCl and NO2, in which KCl is moistened with 2.4% water. Nitrosyl bromide is usually prepared by direct combination of bromine nuth nitric oxide. Nitrosyl chloride and nitrosyl bromide can be prepared by reacting the appropriate potassium halide with nitrogen dioxide at room temperature. The reaction rate increases with increased size of the halide, and NOCl and NOBr can be obtained in a reasonable length of time by powdering the halide salt before adding NO. ... 

CHEMICAL PROPERTIES nonflammable gas contains odd number of electrons and is paramagnetic combines with oxygen to form nitrogen dioxide (NO2), a brown gas combines with chlorine and bromine to form the nitrosyl halides, such as nitrosyl chloride (NOCl) reacts with water to form nitric acid rapidly converted in air to nitrogen dioxide reacts with boron, carbon disulfide, chlorine monoxide, chromium, fluorine, fuels, uranium hydrocarbons, nitrogen trichloride, and phosphine FP (NA) LFL/UFL (NA) AT (NA) HF (-21.5 kcal/mole at 18°C) HK 2.3 kJ/mol at 109.5 K).
