Commun. , 2001, 1400 DOI: 10.1039/B104937M A remarkable pair of macrocyclic amides has been synthesized and crystallographically characterized; these consist of a twelve-membered (N6Na4Mg2)2+ cationic ring host with [C6H3 (CH3)]2- or (C6H4)2- dianionic guests (see picture) derived from toluene and benzene, respectively. 70 70 … Metal amide precursors were purchased from Aldrich Chemical Co. Prior to use in a deposition experiment, 1 mL of precursor was transferred to and stored in a 100-mL stainless steel reservoir under a nitrogen atmosphere. The precursors studied in this report are summarized in Table 1. A set volume, 10 or 20 mL, of metal amide vapor was We recently reported that mixed Li/K metal TMP amide (LiNK metalation conditions) is uniquely suited for the selective achievement of challenging metalations.

The amide group is called a peptide bond when it is part of the main chain of a protein, and isopeptide bond when it occurs in a side chain, such as in the amino acids asparagine and glutamine. It can be viewed as a derivative of a carboxylic acid RCOH with the hydroxyl group –OH replaced by an Written by internationally recognised leaders in the field, Metal Amide Chemistry is the authoritative survey of this important class of compounds, the first since Lappert and Powers 1980 book Metal and Metalloid Amides.

### Valorisation of Renewable Building Blocks via Transition

In some amines, the nitrogen atom replaces a carbon atom in an A pyridine-based amide functionalized tetracarboxylic acid, 5,5′-(pyridine-2, 6-dicarbonyl)bis(azanediyl)}diisophthalic acid (H4L), was synthesized and its coordination chemistry toward zinc(II) and cadmium(II) ions was studied. The reactions of H4L with Zn(NO3)2.6H2O and Cd(NO3)2.4H2O led to its full or partial deprotonation, respectively, and the formation of the 2D … 2021-01-19 2016-12-18 METAL ION COMPLEXING PROPERIES OF AMIDE DONATING LIGANDS Chynthia Janette Siddons A Thesis Submitted to the Krysten Adams.

F. 2014-01-23 00:00:00 Computational investigation of nitrous oxide cleavage by metal–amide systems has shown that a bimetallic mechanism is compatible with the remarkable experimental Amine radical cations, which are an odd-electron species, are of great utility in amine syntheses . They can be formed by loss of an electron from the corresponding amines.

In these two examples, the dimethylamido ligands are both bridging and terminal: Trisaluminium dimer Trisgallium dimer In practice, bulky amide ligands have a lesser tendency to bridge.

Interface chemistry is essential for highly reversible lithium-metal batteries. Here the authors investigate amide-based electrolyte that lead to desirable interface species, resulting in dense A new bio-inspired approach is reported for amide and peptide synthesis using α-amino esters that possess a potential activating group (PAG) at the ester residue. To activate the ester functionality under mild metal-free conditions, we exploited the facile dearomatization of phenols with hypervalent iodine(III) reagents. Using a pyridine–hydrogen fluoride complex, highly reactive acyl fluoride intermediates can be successfully generated, thereby allowing for the smooth formation of Herein, the first general, metal‐free, and highly efficient N‐aryl amide formation is reported from poorly reactive aromatic amines and non‐strained lactones under mild operating conditions using an organic bicyclic guanidine catalyst. This protocol has high application potential as exemplified by the formal syntheses of drug‐relevant An organic photoredox catalyst promotes a metal-, base-, and additive-free amide bond formation reaction in high yields. This green approach offers a broad substrate scope, good compatibility with water and air, and tolerates functional groups such as alcohols, phenols, ethers, esters, halogens, or heterocycles.

It talks about the formation of dimers of metals of the type $\ce{M2}$, because as On the other hand, in sodium amide $\ce{NaNH2}$, sodium is already in the +1 oxidation state and is no longer a reducing agent.However, the amide ion $\ce{NH2-}$ is a very strong base (the $\mathrm pK_\mathrm a$ of ammonia, $\ce{NH3}$, is 38).So $\mathbf{NaNH_2}$ is a way of deprotonating some organic compounds (including terminal alkynes).. The proton attached to the terminal carbon in a Amine oxides are relatively weak bases, pK a ca. 4.5, compared with the parent amine. The coordinate covalent N–O function is polar, with the oxygen being a powerful hydrogen bond acceptor. If one of the alkyl substituents consists of a long chain, such as C 12 H 25 , the resulting amine oxide is an amphoteric surfactant and finds use in shampoos and other mild cleaning agents.
