The main difference is the presence of an electronegative substituent that can act as a leaving group during nucleophile substitution reactions. Although there are many types of carboxylic acid derivatives known we will be focusing on just four: Acid halides, Acid anhydrides, Esters, and Amides. In this article are summarized general properties, synthesis, reactivity, and catalysis of Group 4 transition metal amide complexes. Thermally robust but moisture sensitive compounds of the type M (NR 2) 4 and MY n (NR 2) 4-n [M=Ti, Zr, Hf; R=H, alkyl, aryl; Y=X(halogens), OR; n=1-3) are generally synthesized from MX 4 and amines or alkali metal amides, by disproportionation reactions of M(NR Ambient Moisture Accelerates Hydroamination Reactions of Vinylarenes with Alkali‐Metal Amides under Air.

nitriles, base, hydration, amides. Introduction Metal amides (systematic name metal azanides) are a class of coordination compounds composed of a metal center with amide ligands of the form NR 2 −. Hydrogenation of Alkali and Alkaline Earth Metal Amides enthalpy changes of the reaction of ANH 2 + H 2!AH + NH 3 (A = Li, K, and Ba) were obtained from the van’t Hoff equation.
