Modification of Yttrium Silyl-Bridged Amide Alkyl Complexes through Si-H/C-H Cross-Dehydrocoupling of Silanes with a Silylamino Ligand: Synthesis, Reactivity, and Mechanism was written by You, Qing;Zhang, Jie;Zhou, Xigeng. And the article was included in Chemistry – A European Journal in 2020.COA of Formula: C8H8N2 This article mentions the following:
A new method for the modification of a silylamino ligand was developed through mono and dual C(sp3)-H/Si-H cross-dehydrocoupling with silanes. The reaction of [LY{η2-(C,N)-CH2Si(Me2)NSiMe3}] (L = bis(2,6-diisopropylphenyl)-β-diketiminato, L’ (2L’); L = TpMe2 (2TpMe2)). Also, 1TpMe2 reacted with the secondary silanes Ph2SiH2 and Et2SiH2 to afford the corresponding mono C-H activation products [TpMe2Y{η2-(C,N)-CH(SiHR2)Si(Me2)NSiMe3}] (R = Ph (4b); R = Et (4c)). The equimolar reaction of 1TpMe2 with PhSiH3 also produced the mono C-H activation product 4a ([TpMe2Y{η2-(C,N)-CH(SiH2Ph)Si(Me2)NSiMe3}(THF)]). A study of their reactivity showed that 4a facilely reacted with 2 equiv of benzothiazole by an unusual 1,1-addition of the C:N bond of the benzothiazolyl unit to the Si-H bond to give the C-H/Si-H cross-dehydrocoupling product [(TpMe2)Y{η3-(N,N,N)-N(SiMe3)SiMe2CH2Si(Ph)(CSC6H4N)(CHSC6H4N)}] (5). This modification endows the silylamino ligand with novel reactivity. In the experiment, the researchers used many compounds, for example, 1-Methylbenzimidazole (cas: 1632-83-3COA of Formula: C8H8N2).
1-Methylbenzimidazole (cas: 1632-83-3) belongs to imidazole derivatives. The solubility of imidazoles in ethers is lower than that in alcohols and decreases with increasing chain length of the ethers . In contrast, the solubility of benzimidazoles in alcohols (C3–C6) is higher than in water and generally decreases with a Many drugs contain an imidazole ring, such as certain antifungal drugs, the nitroimidazole series of antibiotics, and the sedative midazolam.COA of Formula: C8H8N2
