The reaction of an aromatic heterocycle with a proton is called a protonation. One of articles about this theory is 《Direct catalytic asymmetric intramolecular conjugate addition of thioamide to α,β-unsaturated ester》. Authors are Suzuki, Yuta; Yazaki, Ryo; Kumagai, Naoya; Shibasaki, Masakatsu.The article about the compound:Mesitylcopper(I)cas:75732-01-3,SMILESS:[Cu]C1=C(C)C=C(C)C=C1C).Name: Mesitylcopper(I). Through the article, more information about this compound (cas:75732-01-3) is conveyed.
A direct catalytic asym. intramol. conjugate addition of thioamide to α,β-unsaturated esters is reported. Catalytic generation of a thioamide enolate with a soft Lewis acid/hard Bronsted base cooperative catalyst was the key to the efficient catalysis. A mesitylcopper/(S)-Xyl-P-Phos catalyst exhibited high catalytic performance.
Although many compounds look similar to this compound(75732-01-3)Name: Mesitylcopper(I), numerous studies have shown that this compound(SMILES:[Cu]C1=C(C)C=C(C)C=C1C), has unique advantages. If you want to know more about similar compounds, you can read my other articles.
