Suda, Takeshi; Noguchi, Keiichi; Tanaka, Ken published the artcile< Rhodium-Catalyzed Asymmetric Formal Olefination or Cycloaddition: 1,3-Dicarbonyl Compounds Reacting with 1,6-Diynes or 1,6-Enynes>, Product Details of C44H40P2, the main research area is dicarbonyl stereoselective olefination diyne enyne rhodium BINAP segphos catalyst.
The Rh(I)/(R)-H8-BINAP complex was used as the catalyst in the asym. intermol. olefination of enolizable 1,3-dicarbonyl compounds with 1,6-diynes by [2+2+2]cycloaddition followed by electrocyclic ring opening. The same reaction was also accomplished with 1,6-enynes by using Rh(I)/S-segphos as catalyst.
Angewandte Chemie, International Edition published new progress about Alkadiynes Role: RCT (Reactant), RACT (Reactant or Reagent). 139139-86-9 belongs to class chiral-phosphine-ligands, and the molecular formula is C44H40P2, Product Details of C44H40P2.
