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.

Metal prices surged 8.4% in June 2020, following a 3.7% rise in May, driven by a confluence of demand recovery in China and supply concerns in Latin America. However, prices are still 5.2% lower than at the start of the year due to the impact of COVID-19. Amine-Rich Metal-Catechol-(Amine) Surface Coating for NO-Generation We selected amine-bearing HD, GPx-like copper ions from CuCl 2 , and adhesive catechol DA as candidate precursors to prepare the Cu II -DA/HD coatings, aiming to catalytically generate NO and provide sufficient reactive amine groups for heparin grafting via carbodiimide chemistry.

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. Further, with few exceptions (Ln 3+ and An 4+ metals with N,N-dialkylacetamides and UO 2+ 2 with acetamide) the majority of any subset of the metal–amide groups examined possess this planar metal–amide structure. 7. 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: alkali metals Reactions of the extremely bulky amido alkali metal complexes, [KL' (η (6)-toluene)], or in situ generated [LiL'] or [LiL″] {L'/ L″ = N (Ar*) (SiR (3)), where Ar* = C (6)H (2) {C (H)Ph (2)} (2)Me-2,6,4 and R = Me (L') or Ph (L″)} with group 13 metal (I) halides Read More.

Amide, any member of either of two classes of nitrogen-containing compounds related to ammonia and amines. The two classes are covalent amides, which are neutral or very weakly acidic substances, and ionic amides, which are strongly alkaline compounds.
