The products formed during exposure of the CH3CONHOH/Ar (AHA/Ar) matrices to the full output of the Xe lamp and to 225 nm OPO radiation are studied. The irradiation promotes the isomerization, 1Z → 1E, and AHA photodissociation reactions. Four

Acetonitrile oxide (2) is produced by the irradiation of the title azirine 1 in the presence of O2 in fluid solutions and in low-temperature matrices through the capture of the biradical 7 with O2, which is generated by the photochem

Reactions of oxygen atoms and acetonitrile have been investigated in solid argon at 14-17 K.Primary photoproducts include hydroxyacetonitrile (HOCH2CN) and acetonitrile N-oxide (CH3CNO).Hydroxyacetonitrile forms hydrogen-bonded complexes with acetonitrile and acetonitrile N-oxide as the secondary products.Acetonitrile N-oxide is suggested to be formed by a simple bimolecular addition reaction of atomic oxygen with the nitrile nitrogen.The participation of O(1D) atoms is considered to increase the yield of hydroxyacetonitrile as compared to acetonitrile N-oxide via H-atom abstraction or insertion reactions.The spectral characteristics of hydroxyacetonitrile, acetonitrile N-oxide, and hydrogen-bonded hydroxyacetonitrile-acetonitrile complex isolated in argon matrices are given.

Primary and tertiary nitronate ions and sulphonyl bromides and iodides rapidly equilibrate with the nitrohalides and sulphinate ion.Products are determined by solvent and by the occurence of cross-equilibrum reactions, some of which have single-electron-transfer mechanism.The reaction of arene-sulphinate and thiolate ions with 1,2-dibromo-2-nitro-1-phenylethane gave E-β-nitrostyrene by Z-philic elimination in both cases, but the more basic thiolate ion also gave, by protophilic elimination, 2-bromo-2-nitro-1-phenylethene.
Kinetics and Mechanism of Oxidation of α-Amino Acids by Bromamine-T in Sulphuric Acid Medium

Kinetics of oxidation of glycine, serine, alanine and leucine by bromamine-T (BAT) have been studied in sulphuric acid (0.05 to 0.15 mol dm-3) at 35 deg C.The reaction shows a first order dependence each in 0, 0 and inverse first order in .Added sulphate ions increase the rate while bisulphate ions retard the reaction.The rate of oxidation increases in the order: leucine > alanine > serine > glycine.The mechanism assumes the interaction of zwitterion of substrate with monobromamine-T in the rate-limiting step.
