Hydride Reduction by a Sodium Hydride–Iodide Composite
Sodium hydride (NaH) is widely used as a Brønsted base in chemical synthesis and reacts with various Brønsted acids, whereas it rarely behaves as a reducing reagent through delivery of the hydride to polar π electrophiles. This study presents a series of reduction reactions of nitriles, amides, and imines as enabled by NaH in the presence of LiI or NaI. This remarkably simple protocol endows Na...
متن کاملA pyrazolate-stabilized sodium hydride complex.
The reaction of a sterically demanding sodium pyrazolate complex with n-butylsodium and diphenylsilane afforded the first well-defined molecular sodium hydride complex [(pz)6Na7H] (pz = 3,5-di-tert-butylpyrazolate) that could be structurally characterised.
متن کاملInverse sodium hydride: a theoretical study.
A recent experimental investigation in which a salt containing the unusual charge distribution H(+) and Na(-) was synthesized and characterized prompted us to undertake an ab initio theoretical investigation. In the salt synthesized, the H(+) is bound to the nitrogen center of an amine and the Na(-) alkalide is "blocked" from approaching the protonated amine site by steric constraints of a cage...
متن کاملRevisiting the Hydrogen Storage Behavior of the Na-O-H System
Solid-state reactions between sodium hydride and sodium hydroxide are unusual among hydride-hydroxide systems since hydrogen can be stored reversibly. In order to understand the relationship between hydrogen uptake/release properties and phase/structure evolution, the dehydrogenation and hydrogenation behavior of the Na-O-H system has been investigated in detail both exand in-situ. Simultaneous...
متن کاملFormation of the imidazolinone ring under mild conditions in the presence of sodium hydride.
Substituted imidazolinones containing heterocyclic carboxylic acids as substituents and possessing herbicidal properties were synthesized by cyclization of 2-amino-2,3-dimethylbutyramide with heterocyclic ethyl dicarboxylates under mild conditions. The use of NaH as base leads to a significant increase in the reaction rate and allows the preparation of the target compounds in high yields.
