  Synthesis of (4Z)-1,1-Diphenyl-1,2,4-heptatrien-6-ynes and Their Facile Cycloaromatizations to α,3-Didehydrotoluene Biradicals Having a Triarylmethyl Radical Center

  摘要：

  The Horner reaction between enynyl aldehydes 12 and phosphinoxy carbanion 11 provided enyne-allenes 14. Thermolysis (37-80 degrees C) of 1,4-cyclohexadiene solutions of 14 gave 20 via alpha,3-didehydrotoluene biradicals 19 having a reactive aryl radical center and a stabilized triaryhmethyl radical center. In the absence of 1,4-cyclohexadiene, 19e underwent intramolecular II-atom transfer between the proximal benzylic methyl group and the aryl radical center to give the more stable biradical 21, the ultimate precursor of 22.
