Fukawa, Naohiro; Osaka, Takuya; Noguchi, Keiichi; Tanaka, Ken published the artcile< Asymmetric Synthesis and Photophysical Properties of Benzopyrano- or Naphthopyrano-Fused Helical Phosphafluorenes>, Electric Literature of 139139-86-9, the main research area is dialkynyl phosphine phenol linked tetrayne chiral rhodium catalyst cycloaddition; benzopyrano fused helical phosphafluorene derivative stereoselective preparation photophys property; naphthol linked tetrayne dialkynyl phosphine chiral rhodium catalyst cycloaddition; naphthopyrano fused helical phosphafluorene derivative stereoselective preparation photophys property; racemic benzopyrano fused helical phosphafluorene derivative crystal mol structure.
Enantioenriched benzopyrano- and naphthopyrano-fused helical phosphafluorenes have been synthesized by the rhodium-catalyzed enantioselective double [2 + 2 + 2] cycloaddition of dialkynyl phosphorus compounds with phenol- or naphthol-linked tetraynes. Photophys. properties of these phosphafluorenes are also disclosed.
