Computed Properties of C38H24F4O4P2. The mechanism of aromatic electrophilic substitution of aromatic heterocycles is consistent with that of benzene. Compound: (R)-5,5′-Bis(diphenylphosphino)-2,2,2′,2′-tetrafluoro-4,4′-bi-1,3-benzodioxole, is researched, Molecular C38H24F4O4P2, CAS is 503538-69-0, about Enantioselective alkynylation of N-sulfonyl α-ketiminoesters via a Friedel-Crafts alkylation strategy.

Enantioselective alkynylation of cyclic N-sulfonyl α-ketiminoesters I (R = H, 5-OMe, 7-Cl, etc.; R1 = Et, Me, i-Pr, n-Bu) with terminal alkynes R2CCH (R2 = C6H5, 3-FC6H4, 4-thien-2-yl, etc.) was developed by using an Ni(ClO4)2/(R)-DTBM-Segphos complex as a catalyst. A range of propargylic amides bearing quaternary stereocenters II was afforded in excellent enantioselectivities (up to 97% ee). Theor. studies revealed that this reaction proceeded via a Friedel-Crafts-type reaction pathway.
There is still a lot of research devoted to this compound(SMILES：FC1(F)OC2=CC=C(P(C3=CC=CC=C3)C4=CC=CC=C4)C(C5=C6OC(F)(F)OC6=CC=C5P(C7=CC=CC=C7)C8=CC=CC=C8)=C2O1)Computed Properties of C38H24F4O4P2, and with the development of science, more effects of this compound(503538-69-0) can be discovered.
