Reactions catalyzed within inorganic and organic materials and at electrochemical interfaces commonly occur at high coverage and in condensed media, causing turnover rates to depend strongly on interfacial structure and composition, 7650-91-1, Name is Benzyldiphenylphosphine, SMILES is P(C1=CC=CC=C1)(CC2=CC=CC=C2)C3=CC=CC=C3, in an article , author is Gu, Jing, once mentioned of 7650-91-1, Safety of Benzyldiphenylphosphine.
Interrupted Morita-Baylis-Hillman-Type Reaction of alpha-Substituted Activated Olefins
It was demonstrated that 3-olefinic oxindoles could generate zwitterionic enolate species with tertiary phosphines and undergo C-C bond formation with various electrophiles in an interrupted Morita-Baylis-Hillman-type reaction manner, followed by a dephosphoration process. Although the in situ formation of phosphorus-ylide intermediates was observed, no Wittig reaction was detected, even in the presence of excess formaldehyde. Moreover, excellent enantioselectivity for the construction of quaternary stereogenic centers was induced with chiral phosphines. Deuterium experiments and density functional theory calculations were conducted to elucidate the reaction mechanism.
But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 7650-91-1, you can contact me at any time and look forward to more communication. Safety of Benzyldiphenylphosphine.
