Landolt-Börnstein Group 2 Molecules and radicals Vol. 18. Radical reaction rates in liquids : supplement to vol. II/13 Subvol. E. 2. Biradicals, radicals in excited states, carbenes and related species / ed.: H. Fischer. Authors: B. R. Arnold ... Buch

Free radicals, which are key intermediates in many thermal, photochemical and radiation processes, are important for a proper understanding of fundamental natural processes and the successful development of organic syntheses. __Volume____II/18__ serves as supplement and extension to __Volume II/13__ and covers rate constants and other kinetic data of free radical reactions in liquids. __II/18__ contains new chapters on reactions of radicals in excited states and of carbenes, nitrenes and analogues. Species in aqueous solutions for which other compilations are available were deliberately omitted as before, and for the same reason electron transfer equilibria of organic radicals were not covered. **II/18E2** contains reaction rate data on biradicals, radicals in excited states, and carbenes and related species. **Contains CD-ROM.** General introduction....Pages 1-5 12.0 General introduction....Pages 1-3 12.1.1 1,3-biradicals....Pages 4-10 12.1.2 1,4-biradicals....Pages 10-21 12.1.3 1,5-biradicals....Pages 21-26 12.1.4 1,6-biradicals....Pages 26-29 12.1.5 alpha,omega-biradicals....Pages 29-42 12.1.6 Other biradicals centered on heteroatoms....Pages 43-53 12.2 Biradical self reactions....Pages 53-54 12.3.1 1,3-biradicals....Pages 55-56 12.3.2 1,4-biradicals (general)....Pages 56-59 12.3.3 1,4-biradicals based on the pyrrol, furan and thiophene structures....Pages 59-72 12.3.4 1,5-biradicals....Pages 72-75 12.3.5 Other biradicals....Pages 75-80 References for 12....Pages 80-82 13.0 Introduction....Pages 83-84 13.1 Intramolecular processes....Pages 84-114 13.2.1 Benzyl and related benzylic radicals....Pages 115-120 13.2.2 Diphenylmethyl, triphenylmethyl and related radicals....Pages 120-135 13.2.3 Ketyl radicals....Pages 136-139 References for 13....Pages 139-140 14.0 Introduction....Pages 141-143 14.1.1 Unimolecular processes....Pages 144-162 14.1.2 Bimolecular reactions....Pages 163-258 Data added in proof....Pages 348-349 14.2.1 Excited triplet carbene....Pages 258-263 14.2.2 Carben rearrangements....Pages 264-266 14.2.3 Carbene self-reactions....Pages 267-268 14.2.4 Triplet carbene-molecule reactions....Pages 268-342 References for 14....Pages 343-347 Remarks, TOCs of Vols. 13 and 18....Pages 1-8 I Organic and inorganic radicals....Pages 1-52 II Not completely identified e{-} and/or OH-adducts to compounds....Pages 1-3 III Radicals derived from polymers and from high molecular biological compounds....Pages 1-2 IV Biradicals....Pages 1-4 V Compounds with known redox potentials....Pages 1-4 VI Carbenes....Pages 1-3 Free radicals, which are key intermediates in many thermal, photochemical and radiation processes, are important for a proper understanding of fundamental natural processes and the successful development of organic syntheses.
