Like many … Pogledajte više LiHMDS is commercially available, but it can also be prepared by the deprotonation of bis(trimethylsilyl)amine with n-butyllithium. This reaction can be performed in situ. HN(Si(CH3)3)2 + C4H9Li → LiN(Si(CH3)3)2 … Pogledajte više Like many organolithium reagents, lithium bis(trimethylsilyl)amide can form aggregates in solution. The extent of aggregation depends on the solvent. In coordinating solvents, such as ethers and amines, the monomer and dimer are prevalent. In … Pogledajte više As a base LiHMDS is often used in organic chemistry as a strong non-nucleophilic base. Its conjugate acid has a pKa of ~26, making it is less basic than other lithium bases, such as LDA (pKa of conjugate acid ~36), but it is more Pogledajte više • Lithium amide • Lithium diisopropylamide • Lithium tetramethylpiperidide Pogledajte više Web15. jan 2024. · Chemical shift values were expressed in ppm (δ) relative to TMS (0 ppm), …
