    Recent advances in the chemistry of ketyl radicals
    Ketyl radicals are valuable reactive intermediates for synthesis and are used extensively to construct complex, functionalized products from carbonyl substrates. Single electron transfer (SET) reduction of the C[double bond, length as m-dash]O bond of aldehydes and ketones is the classical approach ...

    Sensitized photoreduction of selected benzophenones. Mass spectrometry studies of radical cross-coupling reactions
    The hydrogen atom transfer reaction (HAT) between selected benzophenones (benzophenone BP, 3-carboxybenzophenone 3CB, and 4-carboxybenzophenone 4CB) and 2-propanol was reinvestigated focusing on stable product analysis. As expected, the primary species of these HAT's are the respective diphenyl and ...

    Time-resolved EPR studies of the benzophenone—diphenyl kethyl radical system. Possible evidence for quartet—doublet intersystem crossing☆
    The photoreduction of benzophenone by several substrates has been studied by time-resolved EPR. When cyclohexadiene, MTHF, and decane are employed as hydrogen donors to the excited triplet state of benzophenone the diphenyl ketyl radical which is produced exhibits emissive electron spin polarization...

    The laser versus the lamp: Reactivity of the diphenyl ketyl radical in the ground and excited states
    The diphenyl ketyl radical which is formed upon photolysis of α-phenyl benzoin is produced in its excited state upon intense pulsed laser irradiation. Using the techniques of time-resolved absorption and emission spectroscopy, reaction rate constants for the ground and excited states of this radical...

      Which reagent is used to make ketyl radicals?
      Single electron transfer (SET) reduction of the C O bond of aldehydes and ketones is the classical approach for the formation of ketyl radicals and metal reductants are the archetypal reagents employed. The past decade has, however, witnessed significant advances in the generation and harnessing of ketyl radicals.

      Which ketyl radical is produced by PCET?
      Subsequent PCET delivers ketyl radical intermediates 61. The resultant ketyl radicals 61 undergo facile intramolecular radical addition onto the double bond forming a stabilised radical species 62. Hydrogen atom transfer from BT to 62 delivers products 60 and radical 63.

      Is dimethyl ketyl attached to a phenyl ring?
      The MS/MS fragmentation of 2b corresponded to the loss of neutral molecules of water, carbon monoxide, carbon dioxide and aromatic ring and showed a fragmentation peak with m / z 119.0855, identical to the fragment from the photoproduct 1a, therefore suggesting that the dimethyl ketyl is attached to a phenyl ring.

      Are N-heterocyclic carbenes a ketyl radical?
      N-Heterocyclic carbenes (NHCs) are also known to facilitate radical reactions that involve ketyl radicals. In particular, deprotonated Breslow intermediates, generated from aldehydes using NHCs, are useful SET reductants.

      How do ketyl radicals differ from carbonyl compounds?
      The structural properties of ketyl radicals, and their anions, closely resemble carbonyl compounds in terms of bond angle. In contrast, in ketyl radical anions, the C˙–O − bond is longer than a C (sp 2) O, but shorter than a C (sp 3)–O bond.
