Upon irradiation, all the complexes display intense and long-lived luminescence under ambient conditions and in 77-K glass. On the basis of the photophysical and electrochemical data, the emission of most of these complexes is assigned to an excited state of predominantly

• Photochemical Reactions of Halo-/Aryl Sulfide-Substituted Alkyl Phenylglyoxylate, an Assessment of the Lifetime of the Intermediate 1,4-Biradical
  作者：Shengkui Hu、Douglas C. Neckers

  DOI：10.1021/jo971201x

  日期：1997.10.1

  Photochemical reactions of several halo/aryl sulfide-substituted alkyl phenylglyoxylates (1) were studied. For 2'-bromo-(Ib), 2'-iodo- (1c), 2'-(phenylthio)- (1d), and 2'-(phenylsulfinyl)- (1e) ethyl phenylglyoxylate, vinyl phenylglyoxylate (2), proposed to be the result of beta-elimination from the 1,4-biradical formed by triplet state gamma-hydrogen abstraction, is the dominant photoproduct. In the cases Ib and Id Norrish Type II products were also observed. Vinyl phenylglyoxylate (2) was not observed with 2'-chloroethyl (la), 3'-bromopropyl (If), and 3'-(phenylthio)propyl (1g) phenylglyoxylate. The lifetime of the 1,4-biradical intermediate is deduced from the competition between the beta-elimination of the monoradical and the normal biradical decay. The triplet lifetime and the photoreaction efficiency of 1 were not significantly affected by halogen-substitution.
