• Other derivatives have been reported as the quinoid dimer The radical was discovered by Moses Gomberg in 1900 at the University of Michigan. (wikipedia.org)
  • Until Gomberg synthesized triphenylmethyl, free radicals containing carbon had been thought not to exist. (todayinsci.com)
  • Organic free radicals contain a form of carbon with an unpaired electron which allows the radical to react readily with another molecule. (todayinsci.com)
  • Russian-born American chemist who initiated the study of free radicals in chemistry when in 1900 he prepared the first authentic one, triphenylmethyl. (todayinsci.com)
  • It was the first radical ever to be described in organic chemistry. (wikipedia.org)
  • The thiol/lactam combination enables one to generate radicals that can initiate the polymerization of vinyl-based monomers. (eurekaselect.com)
  • The triphenylmethyl radical (often shorted to trityl radical) is an organic compound with the formula (C6H5)3C. (wikipedia.org)
  • It was the first radical ever to be described in organic chemistry. (wikipedia.org)
  • In viscous, organic-rich aerosol particles containing iron, sunlight may induce anoxic conditions that stabilize reactive oxygen species (ROS) and carbon-centered radicals (CCRs). (nature.com)
  • In laboratory experiments, we show mass loss, iron oxidation and radical formation and release from photoactive organic particles containing iron. (nature.com)
  • Our physicochemical kinetic model confirmed these results, implying that oxygen does not penetrate such particles due to the combined effects of fast reaction and slow diffusion near the particle surface, allowing photochemically-produced radicals to be effectively trapped in an anoxic organic matrix.

  • Around 1920, free organic radicals of the triphenylmethyl type were a hot topic. (lindau-nobel.org)
  • The incorporation of terminal alkynes in the chemical structure of persistent organic perchlorotriphenylmethyl (PTM) radicals allows to have new chemical tools to expand their potential applications. (icmab.es)
  • In this work, this is demonstrated by the chemical functionalization of two type of substrates, hydrogenated SiO2-free silicon (Si-H) and gold, and, by exploiting the click chemistry, scarecely used with organic radicals, to synthesise multifunctional systems. (icmab.es)
  • Stimulation of polymerisations by radicals proceeds in such a way that the radical with its free electron is attracted to one side of a double bond, for example in ethylene. (lindau-nobel.org)
  • As a result, one electron is again freed on the other side of the ethylene, which can then repeat the process. (lindau-nobel.org)
  • We find that radicals can attain high concentrations, altering aerosol chemistry and exacerbating health hazards of aerosol exposure. (nature.com)
  • The radical 2 forms a chemical equilibrium with the quinoid-type dimer 3 (Gomberg's dimer). (wikipedia.org)

  • This is known as a radical chain mechanism. (lindau-nobel.org)
  • But the polymerisation of ethylene, which we discovered ten years ago in Mühlheim, does not proceed on the basis of such a radical chain mechanism and is therefore completely unrelated to it. (lindau-nobel.org)
