Lin, Shuang-zheng published the artcileAn efficient one-pot approach to phenanthrene derivatives using a catalyzed tandem Ullmann-pinacol coupling reaction, Application In Synthesis of 286474-59-7, the main research area is ortho haloaryl aldehyde zinc phosphine Ullmann intramol pinacol coupling; trans phenanthrol stereoselective preparation; Ullmann intramol pinacol coupling catalyst phosphine zinc.
In the presence of catalyst (Ph3P)2NiCl2 and reductant Zn, the Ullmann reactions of ortho-halo aryl aldehydes generate biaryl-dialdehydes and zinc halides. Subsequently, ZnX2 can catalyze the intramol. pinacol coupling reaction of biaryl-dialdehydes to form 9,10-dihydrophenanthrene-9,10-diols. One-pot synthesis of 9-phenanthrols can be achieved using this strategy.
Tetrahedron published new progress about Aryl aldehydes Role: RCT (Reactant), RACT (Reactant or Reagent) (o-halo). 286474-59-7 belongs to class chlorides-buliding-blocks, name is 6-Chloro-2-fluoro-3-methylbenzaldehyde, and the molecular formula is C8H6ClFO, Application In Synthesis of 286474-59-7.
