It is commonly abbreviated as LiHMDS or Li(HMDS) (lithium hexamethyldisilazide - a reference to its conjugate acid HMDS) and is primarily used as a strong non-nucleophilic base and as a ligand. 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.

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 north fork taps and corksWeb本发明公开了一种基于吲哚环骨架的手性亚磺酰胺类膦化合物(硼烷保护)Na‑Phos及其制备方法，以吲哚环为骨架，以相应结构的醛3和手性亚磺酰胺4为原料，经过缩合反应、取代反应、加成反应，制得化合物1；本发明使用不同手性亚磺酰胺和不同的亲核试剂，得到(R，RS)、(S，RS)、(R，SS)或(S，SS)四种 ... north fork table and inn southold
