Control experiments and kinetic studies revealed a plausible reaction mechanism, in which amine exchange of 2020-08-21 Heavier alkaline earth (Ae) metal amide complexes Ae(NR2)2 (Ae = Ca, Sr, Ba) were found to be highly active catalysts for hydrogen isotope exchange (HIE). The activities for D/H exchange between C6D6 and H2 strongly increase with metal size (Ca < Sr < Ba) and with amide bulk: N(SiMe3)2 < N(DIPP)(SiiPr3)< N(SiiPr3)2, DIPP = 2,6-diisopropylphenyl. Amide, any member of either of two classes of nitrogen-containing compounds related to ammonia and amines. The covalent amides are neutral or very weakly acidic substances formed by replacement of the hydroxyl group (OH) of an acid by an amino group (NR 2, in which R may represent a hydrogen atom or an organic combining group such as methyl, CH 3).The carboxamides (R′CONR 2), which are 2013-05-04 metal halides, metal amides should be significantly more reactive toward a hydroxylated surface (such as the native oxide on silicon) because the metal-halide bond is significantly stronger than the metal-nitrogen bond (both are weaker than the metal-oxygen bond).29 Metal … Download Citation | Extraction of Precious Metals with a New Amide Extractant | Precious metals are used widely in electronic industry because of their excellent heat resistance, corrosion 2019-08-25 A series of novel salan-ligated rare-earth metal amide complexes were prepared and employed as initiators for the ROP of rac-β-butyrolactone (rac-BBL). Tuning the substituents on the N atoms of the ligand frameworks from aromatic groups to aliphatic groups results in switching tacticity from iso-tactic to syndio-tactic in rac -BBL polymerization.

al Inorganic chemistry, 51 (23), undefined (2012-11-20) Two series of bulky alkaline earth (Ae) metal amide complexes have been prepared: Ae [N (TRIP) 2] 2 (1 ‐Ae) and Ae [N (TRIP) (DIPP)] 2 (2 ‐Ae) (Ae=Mg, Ca, Sr, Ba; TRIP=Si i Pr 3, DIPP=2,6‐diisopropylphenyl). While monomeric 1 ‐Ca was already known, the new complexes have been structurally characterized. Amide compounds have been used as additive to increase the chemical stability against reduced superoxide in Li-air batteries 29, however, systematic exploration of amides as solvents for Li metal Heavier alkaline earth (Ae) metal amide complexes Ae(NR2)2 (Ae = Ca, Sr, Ba) were found to be highly active catalysts for hydrogen isotope exchange (HIE).

Abstract. Conformationally flexible “Carbene–Metal–Amide” (CMA) complexes of copper and gold have been developed based on a combination of sterically hindered cyclic (alkyl) (amino)carbene (CAAC) and 6- and 7-ring heterocyclic amide ligands. These complexes show photoemissions across the visible spectrum with PL quantum yields of up to 89% in Many translated example sentences containing "metal amide" – French-English dictionary and search engine for French translations.

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 Power’s 1980 book “Metal and Metalloid Amides.” An introduction to the topic is followed by in-depth discussions of the amide compounds of: Metal bis(trimethylsilyl)amides (often abbreviated as metal silylamides) are coordination complexes composed of a cationic metal with anionic bis(trimethylsilyl)amide ligands and are part of a broader category of metal amides. As nouns the difference between metal and amide is that metal is any of a number of chemical elements in the periodic table that form a metallic bond with other metal atoms; generally shiny, somewhat malleable and hard, often a conductor of heat and electricity while amide is 1998-03-01 · In 158 out of the 223 instances of oxygen-bound amides, the metal is found to be located within 20° of the plane of the amide.
