The chemical properties of alicyclic heterocycles are similar to those of the corresponding chain compounds. Compound: trans-Di-μ-acetatobis[2-[bis(2-methylphenyl)phosphino]benzyl]dipalladium, is researched, Molecular C46H46O4P2Pd2, CAS is 172418-32-5, about Preparation and Physicochemical Properties of [6]Helicenes Fluorinated at Terminal Rings, the main research direction is fluorinated helicene preparation physicochem property.SDS of cas: 172418-32-5.
The first racemization-stable helicene derivatives fluorinated at terminal rings, 1,2,3,4-tetrafluoro[6]helicene and 1,2,3,4,13,14,15,16-octafluoro[6]helicene, were synthesized via the Wittig reaction followed by oxidative photocyclization in an overall yield of 41% and 76%. The changed electronic structure in fluorinated helicenes was reflected in a slight shift of UV-vis absorption, fluorescence excitation, and emission spectra maxima when compared to unsubstituted [6]helicene. Cyclic voltammetry revealed a moderate decrease in the HOMO-LUMO gap with increasing fluorination. The sp. rotation of tetrafluoro[6]helicene enantiomers was found to be approx. 25% lower than that of unsubstituted [6]helicene. The theor. study of the racemization barrier suggested a reasonable shift toward higher energy with increasing fluorination. The increasing fluorination also significantly affected the intermol. interactions in the crystal lattice. The observed CH···F interactions led to the formation of 1D-mol. chains in the crystal structures of both fluorinated helicenes.
Although many compounds look similar to this compound(172418-32-5)SDS of cas: 172418-32-5, numerous studies have shown that this compound(SMILES:CC1=C([P]2([Pd+2]3([CH2-]C4=C2C=CC=C4)[O-]/C(C)=O[Pd+2]5([O-]/C(C)=O3)[P](C6=C(C)C=CC=C6)(C7=C([CH2-]5)C=CC=C7)C8=C(C)C=CC=C8)C9=C(C)C=CC=C9)C=CC=C1), has unique advantages.
