Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 58656-04-5, is researched, SMILESS is F[B-](F)(F)F.[PH+](C1CCCCC1)(C2CCCCC2)C3CCCCC3, Molecular C18H34BF4PJournal, Article, Organic Letters called The Use of Phosphine Ligands to Control the Regiochemistry of Pd-Catalyzed Hydrostannations of 1-Alkynes: Synthesis of (E)-1-Tributylstannyl-1-alkenes, Author is Darwish, Alla; Lang, Adam; Kim, Thomas; Chong, J. Michael, the main research direction is phosphine cocatalyst regioselectivity effect palladium catalysis hydrostannation terminal alkyne.Computed Properties of C18H34BF4P.
The regiochem. of Pd-catalyzed hydrostannations of terminal alkynes is dramatically influenced by ligand effects. Use of phosphines such as Cy3P, t-Bu2PCH2t-Bu, and t-Bu3P provides (E)-1-tributylstannyl-1-alkenes with regioselectivities up to >99:<1 for substrates where the commonly used Ph3P shows much lower regioselectivities. For example, a 96:4 ratio of (E)-11-(tributylstannyl)undec-10-en-1-ol (87 % yield) to 10-(tributylstannyl)undec-10-en-1-ol was obtained from HO(CH2)9C2H using 0.5 % Pd2(dba)3, 2 % Cy3PHBF4, and 4 % iPr2NEt in toluene at room temperature after 2 h. After consulting a lot of data, we found that this compound(58656-04-5)Computed Properties of C18H34BF4P can be used in many types of reactions. And in most cases, this compound has more advantages.
