Others they made by Wittig or Horner-Wadsworth-Emmons reactions such as the methoxyketone 45 from the phosphonate ester 44. The 78% yield is of pure E-enone 45. [Pg.61]

In 1990, Gorgues and coworkers [60,61] reported the earliest studies of extended TTFs by acetylene scaffolding 61, in order to decrease on-site Coulomb repulsion. The symmetrically substituted acetylenic analog 61 was prepared from a very reactive aldehyde (58) [62] by Wittig or Horner-Wadsworth-Emmons reactions (Scheme 8.8). The CV of 61 exhibited reversible one two-electron redox pan-corresponding to 61/61 . This behavior is different from the TTFVs series of 2, which is linked by an ethylene spacer, due to lack of electronic communication through the acetylenic bond in 61 ". ... [Pg.326]
