Rates of formation of N-bromo amines in aqueous solution
Wajon, Johannes Edmund,Morris, J. Carrell
, p. 4258 - 4263 (1982)
Rates of formation of NH2Br, (CH3)2NBr, N-bromoglycine, and N-bromoglutamate from hypobromite and excess nitrogenous compound were determined in a stopped-flow rapid-kinetics spectrophotometer for the pH range 7-13. The va
Microwave spectroscopy of the NBr radical in the X3Σ- state
Sakamaki,Okabayashi,Tanimoto
, p. 7169 - 7175 (1998)
The pure rotational spectrum of N79Br and N81Br in the electronic ground state was measured. The measurement was carried out using a source-modulated microwave spectrometer with a 2 m free space discharge cell in the frequency region from 213 GHz to 381 GHz. The precise molecular constants including the rotational and the centrifugal distortion constants, the spin-spin and the spin-orbit interaction constants, and the hyperfine coupling constants were accurately determined.
Chemiluminescent reactions of fluorine and chlorine atoms with bromine azide
Coombe, R. D.,Lam, C. H. -T.
, p. 3746 - 3748 (1983)
Chemiluminescence from the reactions of fluorine and chlorine atoms with BrN3 has been observed in a discharge-flow apparatus.The F + BrN3 reaction produces electronically excited BrF(B 3Π0+) in low vibrational levels (υ1Σ+).The only emission observed from the Cl +BrN3 reaction is the b 1Σ+->X 3Σ- transition in NBr.The data are consistent with mechanisms involving attack of the halogen atoms on the nitrogen chain of the azide.The vibrational excitation of the emitting products suggests the heat of formation of BrN3 to be 131+/-2kcal mol-1.

, (2016/08/03)
This invention relates generally to C—H activated ruthenium olefin metathesis catalyst compounds which are stereogenic at the ruthenium center, to their preparation, and the use of such catalysts in the metathesis of olefins and olefin compounds. In particular, the invention relates to the use of C—H activated ruthenium olefin metathesis catalyst compounds in Z-selective olefin metathesis reactions, enantio-selective olefin metathesis reactions, and enantio-Z-selective olefin metathesis reactions. The invention has utility in the fields of catalysis, organic synthesis, polymer chemistry, and industrial and fine chemicals chemistry.

The present invention discloses compounds which, are novel antagonists for melanin-concentrating hormone (MCH), as well as methods for preparing such compounds. In another embodiment, the invention discloses pharmaceutical compositions comprising such MCH antagonists as well as methods of using them to treat obesity, metabolic disorders, eating disorders such as hyperphagia, and diabetes.
Generation of NBr(a1Δ) by the reaction of N3 radicals with Br atoms: A flow reactor source for quenching rate constant measurements
Hewett, Kevin B.,Setser
, p. 335 - 342 (2008/10/08)
The reaction between azide radicals (N3) and Br atoms is shown to produce electronically excited NBr(a1Δ) molecules in a room temperature flow reactor. This chemical system provides adequate concentration of NBr(a1Δ) so that this molecule can be systematically studied. The yield of NBr(b1Σ+) is minor. The quenching reactions of NBr(a) with HCl, HBr, HI, NH3, Br2, CF2Br2, and O2 were examined; the rate constants are (22 ± 5) × 10-14, (280 ± 30) × 10-14, (2300 ± 200) × 10-14, (35 ± 3) × 10-14, (2600 ± 300) × 10-14, (37 ± 6) × 10-14, and (230 ± 30) × 10-14 cm3 molecule-1 s-1, respectively.
